+// - host_class:  supplies context for linkage, access control, protection domain, and class loader
+// - data:  bytes of a class file, a raw memory address (length gives the number of bytes)
+// - cp_patches:  where non-null entries exist, they replace corresponding CP entries in data
+
+// When you load an anonymous class U, it works as if you changed its name just before loading,
+// to a name that you will never use again.  Since the name is lost, no other class can directly
+// link to any member of U.  Just after U is loaded, the only way to use it is reflectively,
+// through java.lang.Class methods like Class.newInstance.
+
+// Access checks for linkage sites within U continue to follow the same rules as for named classes.
+// The package of an anonymous class is given by the package qualifier on the name under which it was loaded.
+// An anonymous class also has special privileges to access any member of its host class.
+// This is the main reason why this loading operation is unsafe.  The purpose of this is to
+// allow language implementations to simulate "open classes"; a host class in effect gets
+// new code when an anonymous class is loaded alongside it.  A less convenient but more
+// standard way to do this is with reflection, which can also be set to ignore access
+// restrictions.
+
+// Access into an anonymous class is possible only through reflection.  Therefore, there
+// are no special access rules for calling into an anonymous class.  The relaxed access
+// rule for the host class is applied in the opposite direction:  A host class reflectively
+// access one of its anonymous classes.
+
+// If you load the same bytecodes twice, you get two different classes.  You can reload
+// the same bytecodes with or without varying CP patches.
+
+// By using the CP patching array, you can have a new anonymous class U2 refer to an older one U1.
+// The bytecodes for U2 should refer to U1 by a symbolic name (doesn't matter what the name is).
+// The CONSTANT_Class entry for that name can be patched to refer directly to U1.
+
+// This allows, for example, U2 to use U1 as a superclass or super-interface, or as
+// an outer class (so that U2 is an anonymous inner class of anonymous U1).
+// It is not possible for a named class, or an older anonymous class, to refer by
+// name (via its CP) to a newer anonymous class.
+
+// CP patching may also be used to modify (i.e., hack) the names of methods, classes,
+// or type descriptors used in the loaded anonymous class.
+
+// Finally, CP patching may be used to introduce "live" objects into the constant pool,
+// instead of "dead" strings.  A compiled statement like println((Object)"hello") can
+// be changed to println(greeting), where greeting is an arbitrary object created before
+// the anonymous class is loaded.  This is useful in dynamic languages, in which
+// various kinds of metaobjects must be introduced as constants into bytecode.
+// Note the cast (Object), which tells the verifier to expect an arbitrary object,
+// not just a literal string.  For such ldc instructions, the verifier uses the
+// type Object instead of String, if the loaded constant is not in fact a String.

+/**
+ * <p>Methods to communicate a client context to MBeans.  A context is
+ * a {@literal Map<String, String>} that is provided by the client and
+ * that an MBean can consult using the {@link #getContext()} method.
+ * The context is set on a per-thread basis and can be consulted by any
+ * code that the target MBean calls within the thread.</p>
+ *
+ * <p>One common usage of client context is to communicate the client's
+ * {@link Locale} to MBeans.  For example, if an MBean has a String attribute
+ * {@code LastProblemDescription}, the value of that attribute could be
+ * a description of the last problem encountered by the MBean, translated
+ * into the client's locale.  Different clients accessing this attribute
+ * from different locales would each see the appropriate version for their
+ * locale.</p>
+ *
+ * <p>The locale case is sufficiently important that it has a special
+ * shorthand, the {@link #getLocale()} method.  This method calls
+ * <code>{@link #getContext()}.get({@link #LOCALE_KEY})</code> and converts the
+ * resultant String into a Locale object.</p>
+ *
+ * <p>Here is what an MBean with a localized {@code LastProblemDescription}
+ * attribute might look like:</p>
+ *
+ * <pre>
+ * public class LocaleSensitive implements LocaleSensitiveMBean {
+ *     ...
+ *     public String getLastProblemDescription() {
+ *         Locale loc = {@link #getLocale() ClientContext.getLocale()};
+ *         ResourceBundle rb = ResourceBundle.getBundle("MyResources", loc);
+ *         String resourceKey = getLastProblemResourceKey();
+ *         return rb.getString(resourceKey);
+ *     }
+ *     ...
+ * }
+ * </pre>
+ *
+ * <p>Here is how a client can communicate its locale to the target
+ * MBean:</p>
+ *
+ * <pre>
+ * JMXConnector connector = JMXConnectorFactory.connect(url);
+ * MBeanServerConnection connection = connector.getMBeanServerConnection();
+ * <b>MBeanServerConnection localizedConnection =
+ *     {@link #withLocale(MBeanServerConnection, Locale)
+ *      ClientContext.withLocale}(connection, Locale.getDefault());</b>
+ * String problem = localizedConnection.getAttribute(
+ *          objectName, "LastProblemDescription");
+ * </pre>
+ *
+ * <p>In the more general case where the client wants to communicate context
+ * other than the locale, it can use {@link #withContext(MBeanServerConnection,
+ * String, String) withContext} instead of {@code withLocale}, and the target
+ * MBean can retrieve the context using {@link #getContext()}.</p>
+ *
+ *
+ * <h3 id="remote-use">Remote use of contexts</h3>
+ *
+ * <p>The various {@code with*} methods, for example {@link
+ * #withLocale(javax.management.MBeanServer, java.util.Locale) withLocale},
+ * transmit the context of each request by encoding it in the ObjectName of
+ * the request.  For example, if a client creates a connection in the
+ * French locale like this...</p>
+ *
+ * <pre>
+ * MBeanServerConnection mbsc = ...;
+ * Locale french = new Locale("fr");
+ * MBeanServerConnection localizedConnection = ClientContext.withLocale(mbsc, french);
+ * </pre>
+ *
+ * <p>...or, equivalently, like this...</p>
+ *
+ * <pre>
+ * MBeanServerConnection localizedConnection =
+ *     ClientContext.withContext(mbsc, {@link #LOCALE_KEY "jmx.locale"}, "fr");
+ * </pre>
+ *
+ * <p>...then the context associates {@code "jmx.locale"} with {@code "fr"}
+ * and a request such as<br>
+ * {@code localizedConnection.getAttribute("java.lang:type=Runtime", "Name")}<br>
+ * is translated into<br>
+ * {@code mbsc.getAttribute("jmx.context//jmx.locale=fr//java.lang:Runtime", "Name")}.<br>
+ * A special {@linkplain javax.management.namespace namespace} {@code jmx.context//}
+ * extracts the context from the string {@code jmx.locale=fr} and establishes
+ * it in the thread that will do<br>
+ * {@code getAttribute("java.lang:Runtime", "Name")}.</p>
+ *
+ * <p>The details of how contexts are encoded into ObjectNames are explained
+ * in the {@link #encode encode} method.</p>
+ *
+ * <p>The namespace {@code jmx.context//} just mentioned is only needed by
+ * remote clients, since local clients can set the context directly using
+ * {@link #doWithContext doWithContext}.  Accordingly, this namespace is not
+ * present by default in the {@code MBeanServer}.  Instead, it is
+ * <em>simulated</em> by the standard RMI connector using a special
+ * {@link MBeanServerForwarder}.  If you are using this connector, you do not
+ * need to do anything special.  Other connectors may or may not simulate this
+ * namespace in the same way.  If the connector server returns true from the
+ * method {@link
+ * javax.management.remote.JMXConnectorServer#supportsSystemMBeanServerForwarder()
+ * supportsSystemMBeanServerForwarder} then it does simulate the namespace.
+ * If you are using another connector, or if you want to be able to use the
+ * {@code with*} methods locally, then you can install the {@code
+ * MBeanServerForwarder} yourself as described in the method {@link
+ * #newContextForwarder newContextForwarder}.</p>

+     * <p>To add description localization to a local {@code MBeanServer}, you

+     *
+     * <pre>
+     * MBeanServer mbs = {@link

+     * ManagementFactory.getPlatformMBeanServer()};  // for example
+     * mbs = ClientContext.newLocalizeMBeanInfoForwarder(mbs);
+     * </pre>
+     *
+     * <li>
+     * <p>To add description localization to a {@linkplain
+     * javax.management.remote.JMXConnectorServer connector server}, you will
+     * need to add both a {@linkplain #newContextForwarder context forwarder}
+     * and a localization forwarder, for example like this:</p>
+     *
+     * <pre>
+     * JMXConnectorServer cs = JMXConnectorServerFactory.newJMXConnectorServer(...);
+     * MBeanServer nextMBS = cs.getMBeanServer();

+     * javax.management.remote.JMXConnectorServer#setMBeanServerForwarder
+     * setMBeanServerForwarder}(contextMBSF);
+     * </pre>
+     *
+     * <p>Notice that the context forwarder must run before the localization
+     * forwarder, so that the locale is correctly established when the latter
+     * runs.  So the {@code nextMBS} parameter of the context forwarder must
+     * be the localization forwarder, and not vice versa.</p>
+     *
+     * <li>
+     * <p>For connectors, such as the standard RMI connector, that support
+     * a {@linkplain
+     * javax.management.remote.JMXConnectorServer#getSystemMBeanServerForwarder
+     * system chain} of {@code MBeanServerForwarder}s, the context forwarder and
+     * the localization forwarder will be installed in that chain, in the right
+     * order, if you include
+     * {@link
+     * javax.management.remote.JMXConnectorServer#LOCALIZE_MBEAN_INFO_FORWARDER
+     * LOCALIZE_MBEAN_INFO_FORWARDER} in the environment {@code Map} with
+     * the value {@code "true"}, for example like this:</p>

+     * the field is the same as {@code locale.toString()}, then this {@code
+     * MBeanInfo} is returned. Otherwise, localization proceeds as follows,
+     * and the {@code "locale"} field in the returned {@code MBeanInfo} will
+     * be {@code locale.toString()}.
+     *
+     * <p>A <em>{@code className}</em> is determined. If this
+     * {@code MBeanInfo} contains a descriptor with the field
+     * <a href="Descriptor.html#interfaceClassName">{@code
+     * "interfaceClassName"}</a>, then the value of that field is the
+     * {@code className}. Otherwise, it is {@link #getClassName()}.
+     * Everything before the last period (.) in the {@code className} is
+     * the <em>{@code package}</em>, and everything after is the <em>{@code
+     * simpleClassName}</em>. (If there is no period, then the {@code package}
+     * is empty and the {@code simpleClassName} is the same as the {@code
+     * className}.)</p>
+     *
+     * <p>A <em>{@code resourceKey}</em> is determined. If this {@code
+     * MBeanInfo} contains a {@linkplain MBeanInfo#getDescriptor() descriptor}
+     * with a field {@link JMX#DESCRIPTION_RESOURCE_KEY_FIELD
+     * "descriptionResourceKey"}, the value of the field is
+     * the {@code resourceKey}. Otherwise, the {@code resourceKey} is {@code
+     * simpleClassName + ".mbean"}.</p>
+     *
+     * <p>A <em>{@code resourceBundleBaseName}</em> is determined. If
+     * this {@code MBeanInfo} contains a descriptor with a field {@link
+     * JMX#DESCRIPTION_RESOURCE_BUNDLE_BASE_NAME_FIELD
+     * "descriptionResourceBundleBaseName"}, the value of the field
+     * is the {@code resourceBundleBaseName}. Otherwise, the {@code
+     * resourceBundleBaseName} is {@code package + ".MBeanDescriptions"}.
+     *
+     * <p>Then, a {@link java.util.ResourceBundle ResourceBundle} is
+     * determined, using<br> {@link java.util.ResourceBundle#getBundle(String,
+     * Locale, ClassLoader) ResourceBundle.getBundle(resourceBundleBaseName,
+     * locale, loader)}. If this succeeds, and if {@link
+     * java.util.ResourceBundle#getString(String) getString(resourceKey)}
+     * returns a string, then that string is the localized description.
+     * Otherwise, the original description is unchanged.</p>
+     *
+     * <p>A localized description for an {@code MBeanAttributeInfo} is
+     * obtained similarly. The default {@code resourceBundleBaseName}
+     * is the same as above. The default description and the
+     * descriptor fields {@code "descriptionResourceKey"} and {@code
+     * "descriptionResourceBundleBaseName"} come from the {@code
+     * MBeanAttributeInfo} rather than the {@code MBeanInfo}. If the
+     * attribute's {@linkplain MBeanFeatureInfo#getName() name} is {@code
+     * Foo} then its default {@code resourceKey} is {@code simpleClassName +
+     * ".attribute.Foo"}.</p>
+     *
+     * <p>Similar rules apply for operations, constructors, and notifications.
+     * If the name of the operation, constructor, or notification is {@code
+     * Foo} then the default {@code resourceKey} is respectively {@code
+     * simpleClassName + ".operation.Foo"}, {@code simpleClassName +
+     * ".constructor.Foo"}, or {@code simpleClassName + ".notification.Foo"}.
+     * If two operations or constructors have the same name (overloading) then
+     * they have the same default {@code resourceKey}; if different localized
+     * descriptions are needed then a non-default key must be supplied using
+     * {@code "descriptionResourceKey"}.</p>
+     *
+     * <p>Similar rules also apply for descriptions of parameters ({@link
+     * MBeanParameterInfo}). The default {@code resourceKey} for a parameter
+     * whose {@linkplain MBeanFeatureInfo#getName() name} is {@code
+     * Bar} in an operation or constructor called {@code Foo} is {@code
+     * simpleClassName + ".operation.Foo.Bar"} or {@code simpleClassName +
+     * ".constructor.Foo.Bar"} respectively.</p>
+     *
+     * <h4>Example</h4>
+     *
+     * <p>Suppose you have an MBean defined by these two Java source files:</p>
+     *
+     * <pre>
+     * // ConfigurationMBean.java
+     * package com.example;
+     * public interface ConfigurationMBean {
+     *     public String getName();
+     *     public void save(String fileName);
+     * }
+     *
+     * // Configuration.java
+     * package com.example;
+     * public class Configuration implements ConfigurationMBean {
+     *     public Configuration(String defaultName) {
+     *         ...
+     *     }
+     *     ...
+     * }
+     * </pre>
+     *
+     * <p>Then you could define the default descriptions for the MBean, by
+     * including a resource bundle called {@code com/example/MBeanDescriptions}
+     * with the compiled classes. Most often this is done by creating a file
+     * {@code MBeanDescriptions.properties} in the same directory as {@code
+     * ConfigurationMBean.java}. Make sure that this file is copied into the
+     * same place as the compiled classes; in typical build environments that
+     * will be true by default.</p>
+     *
+     * <p>The file {@code com/example/MBeanDescriptions.properties} might
+     * look like this:</p>
+     *
+     * <pre>
+     * # Description of the MBean
+     * ConfigurationMBean.mbean = Configuration manager
+     *
+     * # Description of the Name attribute
+     * ConfigurationMBean.attribute.Name = The name of the configuration
+     *
+     * # Description of the save operation
+     * ConfigurationMBean.operation.save = Save the configuration to a file
+     *
+     * # Description of the parameter to the save operation.
+     * # Parameter names from the original Java source are not available,
+     * # so the default names are p1, p2, etc.  If the names were available,
+     * # this would be ConfigurationMBean.operation.save.fileName
+     * ConfigurationMBean.operation.save.p1 = The name of the file
+     *
+     * # Description of the constructor.  The default name of a constructor is
+     * # its fully-qualified class name.
+     * ConfigurationMBean.constructor.com.example.Configuration = <!--
+     * -->Constructor with name of default file
+     * # Description of the constructor parameter.
+     * ConfigurationMBean.constructor.com.example.Configuration.p1 = <!--
+     * -->Name of the default file
+     * </pre>
+     *
+     * <p>Starting with this file, you could create descriptions for the French
+     * locale by creating {@code com/example/MBeanDescriptions_fr.properties}.
+     * The keys in this file are the same as before but the text has been
+     * translated:
+     *
+     * <pre>
+     * ConfigurationMBean.mbean = Gestionnaire de configuration
+     *
+     * ConfigurationMBean.attribute.Name = Le nom de la configuration
+     *
+     * ConfigurationMBean.operation.save = Sauvegarder la configuration <!--
+     * -->dans un fichier
+     *
+     * ConfigurationMBean.operation.save.p1 = Le nom du fichier
+     *
+     * ConfigurationMBean.constructor.com.example.Configuration = <!--
+     * -->Constructeur avec nom du fichier par d&eacute;faut
+     * ConfigurationMBean.constructor.com.example.Configuration.p1 = <!--
+     * -->Nom du fichier par d&eacute;faut
+     * </pre>
+     *
+     * <p>The descriptions in {@code MBeanDescriptions.properties} and
+     * {@code MBeanDescriptions_fr.properties} will only be consulted if
+     * {@code localizeDescriptions} is called, perhaps because the
+     * MBean Server has been wrapped by {@link

+	<h3 id="interop">Interoperability between versions of the JMX
+	  specification</h3>
+
+	<p>When a client connects to a server using the JMX Remote
+	  API, it is possible that they do not have the same version
+	  of the JMX specification.  The version of the JMX
+	  specification described here is version 2.0.  Previous
+	  versions were 1.0, 1.1, 1.2, and 1.4.  (There was no 1.3.)
+	  The standard JMX Remote API is defined to work with version
+	  1.2 onwards, so in standards-based deployment the only
+	  interoperability questions that arise concern version 1.2
+	  onwards.</p>
+
+	<p>Every version of the JMX specification continues to
+	  implement the features of previous versions.  So when the
+	  client is running an earlier version than the server, there
+	  should not be any interoperability concerns.  The only
+	  exception is the unlikely one where a pre-2.0 client used
+	  the string {@code //} in the domain part of an {@link
+	  javax.management.ObjectName ObjectName}.</p>
+
+	<p>When the client is running a later version than the server,
+	  certain newer features may not be available, as detailed in
+	  the next sections.  The method {@link
+	  javax.management.JMX#getSpecificationVersion
+	  JMX.getSpecificationVersion} can be used to determine the
+	  server version to check if required features are
+	  available.</p>
+
+	<h4 id="interop-1.4">If the remote MBean Server is 1.4</h4>

+	      addNotificationListener} since this class did not exist
+	      in 1.4.</p>
+
+	  <li><p>In an attribute in a query, you cannot access values
+	      inside complex types using dot syntax, for example
+	      {@link javax.management.Query#attr Query.attr}{@code
+	      ("HeapMemoryUsage.used")}.</p>
+
+	  <li><p>The packages {@link javax.management.event} and
+	      {@link javax.management.namespace} did not exist in 1.4,
+	      so you cannot remotely create instances of the MBeans
+	      they define.</p>
+
+	  <li><p>Even if the remote MBean Server is 2.0, you cannot in
+	      general suppose that {@link
+	      javax.management.event.EventClient EventClient} or
+	      {@link javax.management.ClientContext ClientContext}
+	      will work there without first checking. If the remote
+	      MBean Server is 1.4 then those checks will return false.
+	      An attempt to use these features without checking will
