Greetings,

Please review this small fix:

Bug: https://bugs.openjdk.java.net/browse/JDK-8158033

Webrev: http://cr.openjdk.java.net/~mgronlun/8158033/webrev/

Description:

The intent when putting in the notify_tracing() hook into debug.cpp
(report_java_out_of_memory()) was to intercept a state believed to be a
VM termination state, especially when OOME is thrown. Since it is
totally valid that Java code catches OOME, and this location actually
goes back to Java, this is the wrong location for this hook.

In addition, the hook should not be typed for OOME only, but generic for
any exit condition (normal / OOME / crash).
This should instead have been put into java.cpp (before_exit()) and in
VMError.cpp (report_vm_die()).

In src/share/vm/runtime/java.cpp why did you move the existing event code? What determined that TRACE_VM_EXIT should happen at that particular point?

I also wonder what TRACE_VM_ERROR might do because in the vmError code it is called in a signal-handling context and so is very limited in what it can legitimately do without potentially messing up the error reporting.

Thanks,
David



Thanks

Markus
