 I would like to backport the fix for 8234270 to 13u:

Bug: https://bugs.openjdk.java.net/browse/JDK-8234270
Original change: https://hg.openjdk.java.net/jdk/jdk/rev/ac6f7738a0ee
Webrev: http://cr.openjdk.java.net/~bae/13u/8234270/webrev.00/

 The original change applies cleanly, except method
MemoryCounter::resize(), where the context needs to be updated due to
absence of the fix for JDK-8234737 (Harmonize parameter order in Atomic
- add) in 13u:

<        Atomic::add(&_size, size_t(sz));
>        Atomic::add(size_t(sz), &_size);

 Tested with tier1 on linux x86_64.
