Thanks for the quick replay.

Yes. I have tried by adding -Xms512m -Xmx2000m -XX:MaxPermSize=128m in mwe2 VM arguments.
But still i am getting the exception.

you might also no use unordered groups but a mixed list instead and use validation and content assist customization to avoid the problem and have the same restrictions
