Please, review the fix for:
https://bugs.openjdk.java.net/browse/JDK-8030027
Open webrev:
http://cr.openjdk.java.net/~sspitsyn/webrevs/2013/hotspot/8030027-JVMTI-HS101.1/
Summary:
The bug is that the JavaThread::last_java_vframe (called from the
VMOp_GetCurrentLocation)
crashes on the target thread stack that is non-walkable because the
thread is exiting.
The fix is to check a condition !_thread->is_exiting() in the
VMOp_GetCurrentLocation.
The fix is for JDK 9.
Looks good to me. I wonder how many more of these termination races are
still lurking.
