| * 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 |
