Hi all,
may I have reviews please for this trivial test fix:
https://bugs.openjdk.java.net/browse/JDK-8224034
http://cr.openjdk.java.net/~stuefe/webrevs/8224034-errorhandlertest-13-fails-intermittently/webrev.00/webrev/
-XX:ErrorHandlerTest=13 may sometimes fail to trigger the expected crash.
We see this on Windows. Where one would expect a ACCESS_VIOLATION, the VM
just quits immediately.
The test jumps to an invalid function pointer. We may see here some sort of
intrusion prevention.
All these tests invoke undefined behavior but the other tests behave in the
expected fashion.
I propose to exclude this case from the test since analyzing why exactly it
quits immediately on Windows could be done but IMHO is not worth the effort.
Thank you!
Thomas
