Hi all,

Please approve jdk8u backport of JDK-8217432.

   JBS: https://bugs.openjdk.java.net/browse/JDK-8217432
   webrev: http://cr.openjdk.java.net/~ysuenaga/JDK-8217432/jdk8u/webrev.00/

This change fixes HWM for Metaspace GC does not exceed MaxMetaspaceSize.
Thus we don't see unexpected Full GC which causes by Metaspace after this change.

This change has been merged to jdk/jdk, and I'm requesting backport it to jdk 11.
Original patch has a change for vmTestbase, but it does not contain in this
approve request because jdk8u does not have it.

I've checked this change works fine on gc/metaspace jtreg tests on Linux x64.
Please approve it.
