Making OpenJDK on Windows Large Address Aware

[Kumar Srinivasan]

Hello Albert,

This really belongs in the hotspot mailing list, as this may need some
VM related changes for the VM to take advantage of the extra memory.

Please see this bug for some details.
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5061380

Note that the above RFE (Request For Enhancement) is looking for
a LAA enabled launcher but there are compatibility issues with Legacy
JNI applications which need to be considered.

IMO: its definitely a good thing to pursue this in the  "OpenJDK on Windows"
project.

Hope this helps.

Kumar
