> Key: HARMONY-4324
> URL: https://issues.apache.org/jira/browse/HARMONY-4324
> Project: Harmony
> Issue Type: Bug
> Components: JDK
> Environment: Windows/x86, Linux/x86, harmony-jdk-r551077
> Reporter: Ivan Popov
> Assignee: Gregory Shimansky
> Attachments: H4324_jdwp_agent.patch

> When JDWP agent receives request for THREAD_START event with modifier for specified thread it calls JVMTI function SetEventNotificationMode() function with given thread. However, JVMTI spec for SetEventNotificationMode() function says:
> The following events cannot be controlled at the thread level
> through this function.
> ...
> - ThreadStart
> ...
> Thus, JDWP agent gets JVMTI_ERROR_ILLEGAL_ARGUMENT (103) error from SetEventNotificationMode().
> Similarly, when JDWP agent handles request for THREAD_DEATH event with specified thread it also calls the JVMTI SetEventNotificationMode() with given thread. But if the thread is not started yet, this function returns JVMTI_ERROR_THREAD_NOT_ALIVE (15) error.
> JDWP agent should handle the THREAD_START/DEATH requests in a special way, for example, to call SetEventNotificationMode() always with null thread and then to filter the THREAD_START/DEATH events.
> This issues causes failure of the following JDWP stress tests:
> org.apache.harmony.test.stress.jpda.jdwp.scenario.EVENT015.EventTest015
> org.apache.harmony.test.stress.jpda.jdwp.scenario.EVENT016.EventTest016
> org.apache.harmony.test.stress.jpda.jdwp.scenario.EVENT017.EventTest017
> Typical error in the tests output:
> ==> Prepare and send requests for THREAD_START and THREAD_END events for 'EventDebuggee015_Thread'...
> ## FAILURE: EventRequest.Set command for THREAD_START event returns unexpected ERROR = 103(ILLEGAL_ARGUMENT)
> ## Expected ERROR = 0(NONE)
> ## Expected ERROR = 110(OUT_OF_MEMORY)
> ## Thread name = EventDebuggee015_Thread
> ==> Time (mlsecs) of preparing requests for THREAD_START and THREAD_END events = 0
> ==> Successful requests for THREAD_START event = 0
> ==> Successful requests for THREAD_END event = 0
> ## FAILURE while sending requests for THREAD_START and THREAD_END events!
