/**
|
|
* The test for the implementation of an object of the type <BR>
|
|
* ThreadReference. <BR>
|
|
* <BR>
|
|
* The test checks up that results of the method <BR>
|
|
* <code>com.sun.jdi.ThreadReference.stop()</code> <BR>
|
|
* complies with its spec. <BR>
|
|
* <BR>
|
|
* The test works as follows. After being started up, <BR> <BR>
|
|
* the debuggee creates a 'lockingObject' for synchronizing threads, <BR>
|
|
* enters a synchronized block in which it creates new thread, thread2, <BR>
|
|
* informs the debugger of the thread2 creation, <BR>
|
|
* and is waiting for reply. <BR>
|
|
* Since the thread2 uses the same locking object in its 'run' method <BR>
|
|
* it is locked up until getting Exception from the debugger. <BR>
|
|
* Upon the receiption a message from the debuggee, <BR>
|
|
* the debugger gets a ThreadReference thread2 mirroring the thread2 and <BR>
|
|
* an ObjectReference throwableObj mirroring a special Throwable object <BR>
|
|
* prepared by the main thread in the debuggee, <BR>
|
|
* (note: for identification, throwableObj.getMessage() returns <BR>
|
|
* the string "testException") <BR>
|
|
* and invokes thread2.stop(throwableObj) which should throw exception <BR>
|
|
* in the locked thread2 in the debugger. <BR>
|
|
* In catch subclouse, the thread2 assigns Exception it got to a special<BR>
|
|
* variable tObj of the Throwable type and ends its running. <BR>
|
|
* The main thread reads tObj.message(), compares to "testException", <BR>
|
|
* and informs the debugger of strings match or mismatch. <BR>
