Request for Approval for CR 7058828 - test/java/util/concurrent/Phaser/Arrive.java fails intermittently

[Chris Hegarty]

This is a request for approval to backport the fix for 7058828 to 
jdk7u-dev/jdk:

     7058828 - test/java/util/concurrent/Phaser/Arrive.java fails 
intermittently
    http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7058828
Changeset in jdk8:
     http://hg.openjdk.java.net/jdk8/tl/jdk/rev/549b7c3f0bdc

The patch for jdk7u is the same as that in jdk8.

Thanks,
Chris
