[jira] Created: (HARMONY-1950) [DRLVM][JVMTI] Java methods called
from JVMTI functions should not generate events
[DRLVM][JVMTI] Java methods called from JVMTI functions should not generate events
----------------------------------------------------------------------------------
Key: HARMONY-1950
URL: http://issues.apache.org/jira/browse/HARMONY-1950
Project: Harmony
Issue Type: Bug
Components: DRLVM
Reporter: Nikolay Kuznetsov
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.

[jira] Updated: (HARMONY-1950) [DRLVM][JVMTI] Java methods called
from JVMTI functions should not generate events
Posted by "Nikolay Kuznetsov (JIRA)" <ji...@apache.org>.
[ 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.
