[10] RFR for JDK-8169961: Memory leak after debugging session

Hi Poonam,

I think this is okay, because with the new change shouldListen() is called right after the thread returns from wait(). And this will lead to the thread immediately exiting. JDWP.VirtualMachine.ReleaseEvents.process(vm); should not be called in this case.

The vm object is used from the outer class TargetVM, as EventController is an inner class of it.

So in my view it's all correct but still somebody of the serviceability group might know better...

Best regards
