* 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
