Sorry I wasn't clear. I just happened to notice that the webrev was parented against JDK9-hs-comp instead of JDK9-hs so I interpreted that to mean that the fix was heading to JDK9-hs-comp first. I don't need the webrev regenerated, but please push to JDK9-hs when the fix has been adequately reviewed and tested.

The current fix/ webrev should work. It does not depend on anything from jdk9-hs-comp. Let me know if you still need the webrev compared against jdk9-hs.
03-05-2016
Since this is an integration_blocker and a PIT failure, this fix needs to be pushed directly to JDK9-hs. Currently the repo is parented against: Compare against: http://hg.openjdk.java.net/jdk9/hs-comp/hotspot/ Does this fix depend on any other changes are in JDK9-hs-comp that are not in JDK9-hs?

Webrev for fix: http://cr.openjdk.java.net/~vdeshpande/8155864/webrev.00/

If there is no simple solution for this we will need to rollback JDK-8152907 changes.

Vivek, please look.

Bumped this bug to P1 since it caused PIT to fail.
03-05-2016
the tests fail only on x64
02-05-2016
most probably caused by JDK-8152907
02-05-2016
the tests fail in both Xmixed and Xcomp mode
