[jira] Updated: (HARMONY-1950) [DRLVM][JVMTI] Java methods called
from JVMTI functions should not generate events
[ http://issues.apache.org/jira/browse/HARMONY-1950?page=all ]
Nikolay Kuznetsov updated HARMONY-1950:
---------------------------------------
Attachment: events.patch
Attached patch fixes this problem, the thread local flag is maintained indicating if TI events should be generated. This flag is checked by ti->isEnabled() thus JVMTI event are not being triggered by this particular thread while wile events are locally disabled.

>
> Several JVMTI functions call java methods during their execution(to query j.l.Thread state for instance). If SINGLE_STEP or METHOD_ENTRY/EXIT events are enabled, this may result in generating these events for internal calls to these java methods.
> While JVMTI spec says nothing about execution of Java code in JVMTI functions, reference implementation does not generates such events. Moreover those
> functions generates events which does not reflect user code behavior and may mislead user JVMTI agents.
> Thus calling Java code from JVMTI function should not result in generating events.
