* <code>com.sun.jdi.ThreadReference.interrupt()</code> <BR>
|
|
* complies with its spec. <BR>
|
|
* <BR>
|
|
* The case for testing includes two tested threads in a debuggee <BR>
|
|
* named thread2 and thread3, and a mirror of thread2 in a debugger. <BR>
|
|
* The method of testing is the comparison of "interrupted status" of <BR>
|
|
* both threads after the method Thread.interrupt() is applied to <BR>
|
|
* thread3 and its "mirroring" method ThreadReference.interrupt() is <BR>
|
|
* applied to the ThreadReference object mirroring thread2. <BR>
|
|
* The test is passed if both 'interrupted status" are equal, <BR>
|
|
* otherwise the test failed. <BR>
|
|
* <BR>
|
|
* The test consists of two cases as follows: <BR>
|
|
* - both debuggee's threads are locked up at synchronized block and <BR>
|
|
* are not suspended; <BR>
|
|
* - both debuggee's threads are locked up at synchronized block and <BR>
|
|
* are suspended by java.lang.Thread.suspend() method; <BR>
