[jira] Commented: (HARMONY-3990) [drlvm][thread]agent test detects the thread event problem

    [ https://issues.apache.org/jira/browse/HARMONY-3990?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12499550 ] 

Ivan Popov commented on HARMONY-3990:
-------------------------------------

I've modified a little attached test to print thread names and eliminate monitor events. I got the following output:

2. run initial class WITH agent
Agent_OnLoad: pVm=010320A0, options=(null)
Agent_OnLoad: OK
 1. VMStart                : pJniEnv=010925B8
 2. VMInit                 : thread=02042790,208D2928,"main" pJniEnv=010925B8
 3. ThreadStart            : thread=01EBB440,208D2928,"main" pJniEnv=010925B8
HELLO.world
 4. ThreadStart            : thread=020C3FF8,208F38E0,"Thread-shutdown" pJniEnv=020BF1D8
 5. ThreadEnd              : thread=020403A8,20900224,"ref handler" pJniEnv=0203C518
    ERROR  : ThreadEnd event for unmatched JNI ptr: 0203C518
 6. ThreadEnd              : thread=02036830,208F8224,"finalizer" pJniEnv=020381D8
    ERROR  : ThreadEnd event for unmatched JNI ptr: 020381D8
 7. VMDeath                : pJniEnv=010925B8

It shows that JVMTI events THREAD_START are missed for "ref handler" and "finalizer" threads.
