Java DirectByteBuffer and OOM

[Seán Coffey]

Biju,

Why don't you pull the patch into your own forest and build a local copy 
? I could be a few weeks/months before this fix becomes public in an 
Oracle JDK release. Oracle jdk7u releases are no longer public. Last 
public one was 7u80.

Regards,
Sean.
