[Petr Pchelko]

Hello, 

This is a request for approval to backport a fix from JDK9 to jdk8u-dev.

The bug: https://bugs.openjdk.java.net/browse/JDK-8048549
The fix: http://cr.openjdk.java.net/~pchelko/9/8048549/webrev.8u/
The 8u fix is different from the 9 version because the workspace have changed. Here's the review of the 8u version:

Thank you.
With best regards. Petr.
