Answer 1

You can configure these arguments for eclipse:

"To solve this I stopped the server in Eclipse. Double clicked on the server in the Servers tab to open the Overview page for the server. Clicked on Open Launch Configuration and then on the Arguments tab.

I added the following VM arguments :

-XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled
