Java DirectByteBuffer and OOM

[Ivan Gerasimov]

Hi Biju!

FYI, the fix was backported to jdk8u with the following two changes:
http://hg.openjdk.java.net/jdk8u/jdk8u-dev/jdk/rev/3d7b2dfd922c
http://hg.openjdk.java.net/jdk8u/jdk8u-dev/jdk/rev/dcc009356125

Please note that currently we've got no plans to backport this to 
earlier releases of jdk.

Sincerely yours,
Ivan
