* @test
*
* @summary converted from VM Testbase nsk/jvmti/GetCurrentContendedMonitor/contmon001.
* VM Testbase keywords: [quick, jpda, jvmti, noras]
* VM Testbase readme:
* DESCRIPTION
* The test exercises JVMTI function GetCurrentContendedMonitor.
* The test cases include:
* - current contended monitor: present or not;
* - thread: current, non-current;
* - thread waiting to enter a monitor or after wait();
* Failing criteria for the test are:
* - object returned by GetCurrentContendedMonitor is not the same
* as expected;
* - failures of used JVMTI functions.
* COMMENTS
* By today, the test is referred from two bugs, 4327280 and 4463667
* To fix bug 4463667, one code fragment with "Thread.sleep(500);"
* is replaced with following one:
* Object obj = new Object();
* *
* *
* synchronized (obj) {
* obj.wait(500);
* }
* Note. Until 4327280 gets fixing, the correction cannot be tested.
* Fixed according to 4509016 bug.
* Fixed according to 4669812 bug.
* The test was fixed due to the following bug:
* 4762695 nsk/jvmti/GetCurrentContendedMonitor/contmon001 has an
* incorrect test
* Ported from JVMDI.
* Fixed according to 4925857 bug:
* - rearranged synchronization of tested thread
* - enhanced descripton
*
* @library /vmTestbase
* /test/lib
* @run driver jdk.test.lib.FileInstaller . .
* @run main/othervm/native -agentlib:contmon001 nsk.jvmti.GetCurrentContendedMonitor.contmon001
