Hi all, Please review a change for JDK-8187033.
Bug report: https://bugs.openjdk.java.net/browse/JDK-8187033 Webrev: http://cr.openjdk.java.net/~horii/8187033/webrev.00/ This change removes a volatile qualifier of a private static variable used by ObjectStreamClass.getClassDataLayout(). Making this variable non-volatile improved performance of GradientBoostingTree test in Intel HiBench [1] by 5% on a POWER8 machine. On an x86 machine, this change did not affect the performance.
