| * @summary converted from VM Testbase nsk/jdi/ObjectReference/disableCollection/disablecollection002. |
| * VM Testbase keywords: [jpda, jdi] |
| * VM Testbase readme: |
| * DESCRIPTION: |
| * The test for the implementation of an object of the type |
| * ObjectReference. |
| * The test checks up that a result of the method |
| * com.sun.jdi.ObjectReference.disableCollection() |
| * complies with its spec: |
| * public void disableCollection() |
| * Prevents garbage collection for this object. |
| * By default all ObjectReference values returned by JDI may be collected at any |
| * time the target VM is running. A call to this method guarantees that |
| * the object will not be collected. |
| * enableCollection() can be used to allow collection once again. |
| * Calls to this method are counted. |
| * Every call to this method requires a corresponding call to enableCollection() |
| * before garbage collection is re-enabled. |
| * Note that while the target VM is suspended, no garbage collection will occur |
| * because all threads are suspended. The typical examination of variables, fields, |
| * and arrays during the suspension is safe without |
| * explicitly disabling garbage collection. |
| * This method should be used sparingly, |
| * as it alters the pattern of garbage collection in the target VM and, consequently, |
| * may result in application behavior under the debugger that |
| * differs from its non-debugged behavior. |
| * The test checks up on the following assertion: |
| * Prevents garbage collection for this object. |
| * By default all ObjectReference values returned by JDI may be collected at |
| * any time the target VM is running. A call to this method guarantees that |
| * the object will not be collected. |
| * The test works as follows: |
| * The debugger program - nsk.jdi.ObjectReference.disableCollection.disablecollection002; |
| * the debuggee program - nsk.jdi.ObjectReference.disableCollection.disablecollection002a. |
| * Using nsk.jdi.share classes, |
| * the debugger gets the debuggee running on another JavaVM, |
| * creates the object debuggee.VM, and waits for VMStartEvent. |
| * Upon getting the debuggee VM started, |
| * the debugger calls corresponding debuggee.VM methods to get |
| * needed data and to perform checks. |
| * In case of error the test produces the return value 97 and |
| * a corresponding error message(s). |
| * Otherwise, the test is passed and produces |
| * the return value 95 and no message. |
