Local refs returned by JVMTI or JNI function can be deleted by DeleteLocalRef. > However according to the test output below DRLVM does not return local ref. As a result it crashes some time after DeleteLocalRef for the owner of the jvmtiMonitorUsage structure. The same is for waiters/notify_waiters. SUN and JRockit work fine in this situation. > DRLVM>>> > ========================================================================================= > 2. run initial class WITH agent > Agent_OnLoad: pVM=010020A0, options=(null) > Agent_OnLoad: OK > 1.
