Re: synchronization of JVMTI phase notifications [Fwd: Data visibility between threads in Hotspot]

[Daniel D. Daugherty]

Hiroshi, Do you have a test program for this problem? That would help with my analysis of the code paths... Dan Hiroshi Yamauchi wrote: There are two bugs: 1. A CompiledMethodLoad event is sent after the VM death event. 2. SetEventCallbacks and SetEventNotificationMode calls may not be respected because of the race condition/visibility issue. Delaying the posting of the VM death event will probably fix bug 1 and we can probably avoid using mutex locks in event posting. But I suspect that fixing bug 2 will need mutex locks after all. Is there a way around mutex locks here? Thanks, Hiroshi
