* DESCRIPTION
* The test exercises JVMTI function GetThreadState. Java program
* launchs thread and 3 times calls a native method checkStatus. This
* method calls GetThreadState and checks if the returned value is
* correct.
* The test exercises JVMTI function GetThreadState. Java program
* launches a thread and 3 times calls a native method checkStatus.
* This method calls GetThreadState and checks if the returned value is:
* - JVMTI_THREAD_STATE_RUNNABLE
* if thread is runnable
* - JVMTI_THREAD_STATE_BLOCKED_ON_MONITOR_ENTER
* if thread is waiting to enter sync. block
* - JVMTI_THREAD_STATE_IN_OBJECT_WAIT
* if thread is waiting by object.wait()
* The test also enables JVMPI_EVENT_METHOD_ENTRY and JVMPI_EVENT_METHOD_EXIT
* events and checks if GetThreadState returns JVMPI_THREAD_RUNNABLE for
* their threads.
* Failing criteria for the test are:
* - value returned by GetThreadState does not match expected value;
* - failures of used JVMTI functions.
* COMMENTS
* Converted the test to use GetThreadState instead of GetThreadStatus.
* The test was updated to be more precise in its thread state transitions.
* Fixed according to 4387521 bug.
* To fix bug 4463667,
* 1) two code fragments with "Thread.sleep(500);" are replaced
* with following ones:
* Object obj = new Object();
* *
* *
* synchronized (obj) {
* obj.wait(500);
* }
* 2) extra waiting time
* synchronized (obj) {
* obj.wait(500);
* }
* is added to get waiting time certainly after "contendCount"
* is set to 1.
* Fixed according to 4669812 bug.
* Ported from JVMDI.
* Fixed according to 4925857 bug:
* - rearranged synchronization of tested thread
* - enhanced descripton
