| /** |
| * The test for the implementation of an object of the type <BR> |
| * ThreadGroupReference. <BR> |
| * <BR> |
| * The test checks up that results of the method <BR> |
| * <code>com.sun.jdi.ThreadGroupReference.threads()</code> <BR> |
| * complies with its spec. <BR> |
| * <BR> |
| * The case for testing includes two ThreadGroup objects defined <BR> |
| * in a debuggee and their mirrors in a debugger. <BR> |
| * Parenthood relationships between the objects are as follows: <BR> |
| * threadGroup2 is a subgroup of mainParent <group> <BR> |
| * The objects are created together with three debuggee's threads; <BR> |
| * the main thread and a thread2 belong to the mainParent group, <BR> |
| * whereas a thread3 to the subgroup. <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 two new threads, <BR> |
| * informs the debugger of the threads creation, <BR> |
| * and is waiting for reply. <BR> |
| * Since the threads use the same locking object in their 'run' methods <BR> |
| * they are locked up until main thread leaves the synchronized block. <BR> |
| * Upon the receiption a message from the debuggee, <BR> |
| * the debugger gets Lists of threads in each of the groups, <BR> |
| * and checks up the sizes of Lists and names of ThreadReference objects<BR> |
| * in the List returned by the tested method, <BR> |
| * that is, mainParent.threads(). <BR> |
