Hi all,

Could I get a review for this small change for the except* tests:

Webrev: http://cr.openjdk.java.net/~jcbeyler/8213721/webrev.00/
Bug: https://bugs.openjdk.java.net/browse/JDK-8213721

The bug contains a good explanation of why this is required.

After the webrev, the tests no longer fail due to a SIGSEV with the flags:

-XX:+UnlockExperimentalVMOptions -XX:+EnableJVMCI -XX:+UseJVMCICompiler
-XX:+TraceExceptions -Dgraal.PrintCompilation=true -XX:+PrintCompilation
-XX:+TraceDeoptimization

(except010.java failed due to a timeout and except004.java failed due to
an OOME from a Graal thread).

Thanks,
Jc

Hi JC,
I think you need to send this to runtime-dev.
