[jira] Updated: (HARMONY-4905) Last thread event before stick in Join is incorrect

     [ https://issues.apache.org/jira/browse/HARMONY-4905?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alexander N. Alexeev updated HARMONY-4905:
------------------------------------------

    Description: 
When one thread spawns another and joins it, waiting for its
termination, it becomes blocked on monitor  (from last handled event
JVMTI_EVENT_MONITOR_CONTENDED_ENTER for that thread before 'sleep") ,
while in other VMs (Sun's, IBM's and BEA's) thread which calls "Join"
starts waiting (last event is JVMTI_EVENT_MONITOR_WAIT before
'sleep"). Probably set of events depends on VM internals, but in
common sense "waited" state is more suitable for thread which waits
for other thread termination.

Events sequence can be seen at attached event_log.txt, place in  trace where Join happens is marked.
