+ * Due to the lazy class linking performed by many VMs, it is

+ * before the associated class is loaded. Until the class is loaded
+ * all that is available is a signature string. If an attempt is made to
+ * set the value of such a field or variable from JDI, the appropriate
+ * type checking cannot be done because the destination class has not been
+ * loaded. The same is true for the element class of array elements.
+ * <p>
+ * It is not advisable to solve this problem by attempting a class load on
+ * the fly in this case. There are two problems in having the debugger load
+ * a class instead of waiting for it to load over the normal course
+ * of events.
+ * <ul>
+ * <li>There can be no guarantee that running the appropriate class
+ * loader won't cause a deadlock in loading the
+ * class. Class loaders can consist of arbitrary
+ * Java<sup><font size=-2>TM</font></sup> programming language code and the
+ * class loading methods are usually synchronized. Most of the work
+ * done by a debugger happens when threads are suspended. If another
+ * application thread is suspended within the same class loader,
+ * a deadlock is very possible.
+ * <li>Changing the order in which classes are normally loaded may either mask
+ * or reveal bugs in the application. An unintrusive debugger should strive
+ * to leave unchanged the behavior of the application being debugged.
+ * </ul>
+ * To avoid these potential problems, this exception is thrown.
+ * <p>
+ * Note that this exception will be thrown until the class in question
+ * is visible to the class loader of enclosing class. (That is, the

+ * (This implies that the argument type must be loaded through the

+ * If the method being called accepts a variable number of arguments,
+ * then the last argument type is an array of some component type.
+ * The argument in the matching position can be omitted, or can be null,
+ * an array of the same component type, or an argument of the
+ * component type followed by any number of other arguments of the same
+ * type. If the argument is omitted, then a 0 length array of the
+ * component type is passed. The component type can be a primitive type.

+ * By default, all threads in the target VM are resumed while

+ * suspended by an event or by {@link VirtualMachine#suspend} or
+ * {@link ThreadReference#suspend}. This is done to prevent the deadlocks
+ * that will occur if any of the threads own monitors
+ * that will be needed by the invoked method.
+ * Note, however, that this implicit resume acts exactly like
+ * {@link ThreadReference#resume}, so if the thread's suspend
+ * count is greater than 1, it will remain in a suspended state
+ * during the invocation and thus a deadlock could still occur.
+ * By default, when the invocation completes,
+ * all threads in the target VM are suspended, regardless their state
+ * before the invocation.
+ * It is possible that
+ * breakpoints or other events might occur during the invocation.
+ * This can cause deadlocks as described above. It can also cause a deadlock
+ * if invokeMethod is called from the client's event handler thread. In this
+ * case, this thread will be waiting for the invokeMethod to complete and
+ * won't read the EventSet that comes in for the new event. If this
+ * new EventSet is SUSPEND_ALL, then a deadlock will occur because no
+ * one will resume the EventSet. To avoid this, all EventRequests should
+ * be disabled before doing the invokeMethod, or the invokeMethod should
+ * not be done from the client's event handler thread.
+ * <p>
+ * The resumption of other threads during the invocation can be prevented
+ * by specifying the {@link #INVOKE_SINGLE_THREADED}
+ * bit flag in the <code>options</code> argument; however,
+ * there is no protection against or recovery from the deadlocks
+ * described above, so this option should be used with great caution.
+ * Only the specified thread will be resumed (as described for all
+ * threads above). Upon completion of a single threaded invoke, the invoking thread
+ * will be suspended once again. Note that any threads started during
+ * the single threaded invocation will not be suspended when the
+ * invocation completes.
+ * <p>
+ * If the target VM is disconnected during the invoke (for example, through
+ * {@link VirtualMachine#dispose}) the method invocation continues.

+ * A point within the executing code of the target VM.
+ * Locations are used to identify the current position of
+ * a suspended thread (analogous to an instruction pointer or
+ * program counter register in native programs). They are also used
+ * to identify the position at which to set a breakpoint.
+ * <p>
+ * The availability of a line number for a location will

+ * <p>
+ * <a name="strata"><b>Strata</b></a>
+ * <p>
+ * The source information for a Location is dependent on the
+ * <i>stratum</i> which is used. A stratum is a source code
+ * level within a sequence of translations. For example,
+ * say the baz program is written in the programming language
+ * "Foo" then translated to the language "Bar" and finally
+ * translated into the Java programming language. The
+ * Java programming language stratum is named
+ * <code>"Java"</code>, let's say the other strata are named
+ * "Foo" and "Bar". A given location (as viewed by the
+ * {@link #sourceName()} and {@link #lineNumber()} methods)
+ * might be at line 14 of "baz.foo" in the <code>"Foo"</code>
+ * stratum, line 23 of "baz.bar" in the <code>"Bar"</code>
+ * stratum and line 71 of the <code>"Java"</code> stratum.
+ * Note that while the Java programming language may have
+ * only one source file for a reference type, this restriction
+ * does not apply to other strata - thus each Location should
+ * be consulted to determine its source path.
+ * Queries which do not specify a stratum
+ * ({@link #sourceName()}, {@link #sourcePath()} and
+ * {@link #lineNumber()}) use the VM's default stratum
+ * ({@link VirtualMachine#getDefaultStratum()}).
+ * If the specified stratum (whether explicitly specified
+ * by a method parameter or implicitly as the VM's default)
+ * is <code>null</code> or is not available in the declaring
+ * type, the declaring type's default stratum is used
+ * ({@link #declaringType()}.{@link ReferenceType#defaultStratum()
+ * defaultStratum()}). Note that in the normal case, of code
+ * that originates as Java programming language source, there
+ * will be only one stratum (<code>"Java"</code>) and it will be
+ * returned as the default. To determine the available strata
+ * use {@link ReferenceType#availableStrata()}.

+ * Method invocation is not supported
+ * when the target VM has been suspended through

+ * is suspended through {@link ThreadReference#suspend}.
+ * <p>
+ * The specified method is invoked with the arguments in the specified
+ * argument list. The method invocation is synchronous; this method
+ * does not return until the invoked method returns in the target VM.

+ * The argument in the matching position can be omitted, or can be null,
+ * an array of the same component type, or an argument of the
+ * component type followed by any number of other arguments of the same
+ * type. If the argument is omitted, then a 0 length array of the
+ * component type is passed. The component type can be a primitive type.
+ * Autoboxing is not supported.
+ *
+ * See section 5.2 of
+ * <cite>The Java™ Language Specification</cite>
+ * for more information on assignment compatibility.
+ * <p>
+ * By default, the method is invoked using dynamic lookup as
+ * documented in section 15.12.4.4 of
+ * <cite>The Java™ Language Specification</cite>
+ * in particular, overriding based on the runtime type of the object
+ * mirrored by this {@link ObjectReference} will occur. This
+ * behavior can be changed by specifying the
+ * {@link #INVOKE_NONVIRTUAL} bit flag in the <code>options</code>
+ * argument. If this flag is set, the specified method is invoked
+ * whether or not it is overridden for this object's runtime type.
+ * The method, in this case, must have an implementation, either in a class
+ * or an interface. This option is useful for performing method invocations
+ * like those done with the <code>super</code> keyword in the Java programming
+ * language.
+ * <p>
+ * By default, all threads in the target VM are resumed while
+ * the method is being invoked if they were previously
+ * suspended by an event or by {@link VirtualMachine#suspend} or
+ * {@link ThreadReference#suspend}. This is done to prevent the deadlocks
+ * that will occur if any of the threads own monitors
+ * that will be needed by the invoked method.
+ * Note, however, that this implicit resume acts exactly like
+ * {@link ThreadReference#resume}, so if the thread's suspend
+ * count is greater than 1, it will remain in a suspended state
+ * during the invocation and thus a deadlock could still occur.
+ * By default, when the invocation completes,
+ * all threads in the target VM are suspended, regardless their state
+ * before the invocation.
+ * It is possible that
+ * breakpoints or other events might occur during the invocation.
+ * This can cause deadlocks as described above. It can also cause a deadlock
+ * if invokeMethod is called from the client's event handler thread. In this
+ * case, this thread will be waiting for the invokeMethod to complete and
+ * won't read the EventSet that comes in for the new event. If this
+ * new EventSet is SUSPEND_ALL, then a deadlock will occur because no
+ * one will resume the EventSet. To avoid this, all EventRequests should
+ * be disabled before doing the invokeMethod, or the invokeMethod should
+ * not be done from the client's event handler thread.
+ * <p>
+ * The resumption of other threads during the invocation can be prevented
+ * by specifying the {@link #INVOKE_SINGLE_THREADED}
+ * bit flag in the <code>options</code> argument; however,
+ * there is no protection against or recovery from the deadlocks
+ * described above, so this option should be used with great caution.
+ * Only the specified thread will be resumed (as described for all
+ * threads above). Upon completion of a single threaded invoke, the invoking thread
+ * will be suspended once again. Note that any threads started during
+ * the single threaded invocation will not be suspended when the

+ * A virtual machine targeted for debugging.
+ * More precisely, a {@link Mirror mirror} representing the
+ * composite state of the target VM.
+ * All other mirrors are associated with an instance of this
+ * interface. Access to all other mirrors is achieved
+ * directly or indirectly through an instance of this
+ * interface.
+ * Access to global VM properties and control of VM execution
+ * are supported directly by this interface.
+ * <P>
+ * Instances of this interface are created by instances of
+ * {@link com.sun.jdi.connect.Connector}. For example,
+ * an {@link com.sun.jdi.connect.AttachingConnector AttachingConnector}
+ * attaches to a target VM and returns its virtual machine mirror.
+ * A Connector will typically create a VirtualMachine by invoking
+ * the VirtualMachineManager's {@link
+ * com.sun.jdi.VirtualMachineManager#createVirtualMachine(Connection)}
+ * createVirtualMachine(Connection) method.
+ * <p>
+ * Note that a target VM launched by a launching connector is not
+ * guaranteed to be stable until after the {@link com.sun.jdi.event.VMStartEvent} has been
+ * received.
+ * <p>
+ * Any method on <code>VirtualMachine</code> which
+ * takes <code>VirtualMachine</code> as an parameter may throw
+ * {@link com.sun.jdi.VMDisconnectedException} if the target VM is
+ * disconnected and the {@link com.sun.jdi.event.VMDisconnectEvent} has been or is
+ * available to be read from the {@link com.sun.jdi.event.EventQueue}.
+ * <p>
+ * Any method on <code>VirtualMachine</code> which
+ * takes <code>VirtualMachine</code> as an parameter may throw
+ * {@link com.sun.jdi.VMOutOfMemoryException} if the target VM has run out of memory.

+/**
+ * A manager of connections to target virtual machines. The
+ * VirtualMachineManager allows one application to debug
+ * multiple target VMs. (Note that the converse is not
+ * supported; a target VM can be debugged by only one
+ * debugger application.) This interface
+ * contains methods to manage connections
+ * to remote target VMs and to obtain the {@link VirtualMachine}
+ * mirror for available target VMs.
+ * <p>
+ * Connections can be made using one of several different
+ * {@link com.sun.jdi.connect.Connector} objects. Each connector encapsulates
+ * a different way of connecting the debugger with a target VM.
+ * <p>
+ * The VirtualMachineManager supports many different scenarios for
+ * connecting a debugger to a virtual machine. Four examples
+ * are presented in the table below. The
+ * examples use the command line syntax in Sun's implementation.
+ * Some {@link com.sun.jdi.connect.Connector} implementations may require slightly
+ * different handling than presented below.

+ *
+ * <p> Connectors are created at start-up time. That is, they
+ * are created the first time that {@link
+ * com.sun.jdi.Bootstrap#virtualMachineManager()} is invoked.
+ * The list of all Connectors created at start-up time can be
+ * obtained from the VirtualMachineManager by invoking the
+ * {@link #allConnectors allConnectors} method.
+ *
+ * <p> Connectors are created at start-up time if they are
+ * installed on the platform. In addition, Connectors are created
+ * automatically by the VirtualMachineManager to encapsulate any
+ * {@link com.sun.jdi.connect.spi.TransportService} implementations
+ * that are installed on the platform. These two mechanisms for
+ * creating Connectors are described here.
+ *
+ * <p> A Connector is installed on the platform if it is installed
+ * in a jar file that is visible to the defining class loader of
+ * the {@link com.sun.jdi.connect.Connector} type,
+ * and that jar file contains a provider configuration file named
+ * <tt>com.sun.jdi.connect.Connector</tt> in the resource directory
+ * <tt>META-INF/services</tt>, and the provider configuration file
+ * lists the full-qualified class name of the Connector
+ * implementation. A Connector is a class that implements the
+ * {@link com.sun.jdi.connect.Connector Connector} interface. More
+ * appropriately the class implements one of the specific Connector
+ * types, namely {@link com.sun.jdi.connect.AttachingConnector
+ * AttachingConnector}, {@link com.sun.jdi.connect.ListeningConnector
+ * ListeningConnector}, or {@link com.sun.jdi.connect.LaunchingConnector
+ * LaunchingConnector}. The format of the provider configuration file
+ * is one fully-qualified class name per line. Space and tab characters
+ * surrounding each class, as well as blank lines are ignored. The
+ * comment character is <tt>'#'</tt> (<tt>0x23</tt>), and on each
+ * line all characters following the first comment character are
+ * ignored. The file must be encoded in UTF-8.
+ *
+ * <p> At start-up time the VirtualMachineManager attempts to load
+ * and instantiate (using the no-arg constructor) each class listed
+ * in the provider configuration file. Exceptions thrown when loading
+ * or creating the Connector are caught and ignored. In other words,
+ * the start-up process continues despite of errors.
+ *
+ * <p> In addition to Connectors installed on the platform the
+ * VirtualMachineManager will also create Connectors to encapsulate
+ * any {@link com.sun.jdi.connect.spi.TransportService} implementations
+ * that are installed on the platform. A TransportService is
+ * installed on the platform if it installed in a jar file that is
+ * visible to the defining class loader for the
+ * {@link com.sun.jdi.connect.spi.TransportService} type, and that jar
+ * file contains a provider configuration file named
+ * <tt>com.sun.jdi.connect.spi.TransportService</tt> in the resource
+ * directory <tt>META-INF/services</tt>, and the provider
+ * configuration file lists the the full-qualified class name of the
+ * TransportService implementation. A TransportService is a concrete
+ * sub-class of {@link com.sun.jdi.connect.spi.TransportService
+ * TransportService}. The format of the provider configuration file
+ * is the same as the provider configuration file for Connectors
+ * except that each class listed must be the fully-qualified class
+ * name of a class that implements the TransportService interface.
+ *
+ * <p> For each TransportService installed on the platform, the
+ * VirtualMachineManager creates a corresponding
+ * {@link com.sun.jdi.connect.AttachingConnector} and
+ * {@link com.sun.jdi.connect.ListeningConnector}. These
+ * Connectors are created to encapsulate a {@link
+ * com.sun.jdi.connect.Transport Transport} that in turn
+ * encapsulates the TransportService.
+ * The AttachingConnector will be named based on the name of the
+ * transport service concatenated with the string <tt>Attach</tt>.
+ * For example, if the transport service {@link
+ * com.sun.jdi.connect.spi.TransportService#name() name()} method
+ * returns <tt>telepathic</tt> then the AttachingConnector will
+ * be named <tt>telepathicAttach</tt>. Similiarly the ListeningConnector
+ * will be named with the string <tt>Listen</tt> tagged onto the
+ * name of the transport service. The {@link
+ * com.sun.jdi.connect.Connector#description() description()} method
+ * of both the AttachingConnector, and the ListeningConnector, will
+ * delegate to the {@link com.sun.jdi.connect.spi.TransportService#description()
+ * description()} method of the underlying transport service. Both
+ * the AttachingConnector and the ListeningConnector will have two
+ * Connector {@link com.sun.jdi.connect.Connector$Argument Arguments}.
+ * A {@link com.sun.jdi.connect.Connector$StringArgument StringArgument}
+ * named <tt>address</tt> is the connector argument to specify the
+ * address to attach too, or to listen on. A
+ * {@link com.sun.jdi.connect.Connector$IntegerArgument IntegerArgument}
+ * named <tt>timeout</tt> is the connector argument to specify the
+ * timeout when attaching, or accepting. The timeout connector may be
+ * ignored depending on if the transport service supports an attach
+ * timeout or accept timeout.
+ *
+ * <p> Initialization of the virtual machine manager will fail, that is
+ * {@link com.sun.jdi.Bootstrap#virtualMachineManager()} will throw an
+ * error if the virtual machine manager is unable to create any
+ * connectors.

+ * A transport service for connections between a debugger and
+ * a target VM.
+ *
+ * <p> A transport service is a concrete subclass of this class
+ * that has a zero-argument constructor and implements the abstract
+ * methods specified below. It is the underlying service
+ * used by a {@link com.sun.jdi.connect.Transport} for
+ * connections between a debugger and a target VM.
+ *
+ * <p> A transport service is used to establish a connection
+ * between a debugger and a target VM, and to transport Java
+ * Debug Wire Protocol (JDWP) packets over an underlying
+ * communication protocol. In essence a transport service
+ * implementation binds JDWP (as specified in the
+ * <a href="../../../../../../../../../technotes/guides/jpda/jdwp-spec.html">
+ * JDWP specification</a>) to an underlying communication
+ * protocol. A transport service implementation provides
+ * a reliable JDWP packet transportation service. JDWP
+ * packets are sent to and from the target VM without duplication
+ * or data loss. A transport service implementation may be
+ * based on an underlying communication protocol that is
+ * reliable or unreliable. If the underlying communication
+ * protocol is reliable then the transport service implementation
+ * may be relatively simple and may only need to transport JDWP
+ * packets as payloads of the underlying communication
+ * protocol. In the case of an unreliable communication
+ * protocol the transport service implementation may include
+ * additional protocol support in order to ensure that packets
+ * are not duplicated and that there is no data loss. The
+ * details of such protocols are specific to the implementation
+ * but may involve techniques such as the <i>positive
+ * acknowledgment with retransmission</i> technique used in
+ * protocols such as the Transmission Control Protocol (TCP)
+ * (see <a href="http://www.ietf.org/rfc/rfc0793.txt"> RFC 793
+ * </a>).
+ *
+ * <p> A transport service can be used to initiate a connection
+ * to a target VM. This is done by invoking the {@link #attach}
+ * method. Alternatively, a transport service can listen and
+ * accept connections initiated by a target VM. This is done
+ * by invoking the {@link #startListening(String)} method to
+ * put the transport into listen mode. Then the {@link #accept}
+ * method is used to accept a connection initiated by a

+ * The collection of existing event requests is
+ * managed by the {@link EventRequestManager}.
+ * <p>
+ * The number of events generated for an event request can be controlled
+ * through filters. Filters provide additional constraints that an event
+ * must satisfy before it is placed on the event queue. Multiple filters can
+ * be used by making multiple calls to filter addition methods such as
+ * {@link ExceptionRequest#addClassFilter(java.lang.String classPattern)}.
+ * Filters are added to an event one at a time only while the event is
+ * disabled. Multiple filters are applied with CUT-OFF AND, in the order
+ * it was added to the request. Only events that satisfy all filters are
+ * placed in the event queue.
+ * <p>
+ * The set of available filters is dependent on the event request,
+ * some examples of filters are:
+ * <ul>
+ * <li>Thread filters allow control over the thread for which events are
+ * generated.
+ * <li>Class filters allow control over the class in which the event
+ * occurs.
+ * <li>Instance filters allow control over the instance in which
+ * the event occurs.
+ * <li>Count filters allow control over the number of times an event
+ * is reported.
+ * </ul>
+ * Filters can dramatically improve debugger performance by reducing the
+ * amount of event traffic sent from the target VM to the debugger VM.
+ * <p>
+ * Any method on <code>EventRequest</code> which
+ * takes <code>EventRequest</code> as an parameter may throw
