Eclipse hanging, how to kill it properly?

Question

Sometimes my Eclipse hangs and I need to kill it violently. However, I have been unable to do it properly. It seems that kill -9 does not actually shut it down in a proper way since I can still see the hanged window. What command sequence would kill my Eclipse properly so I could restart it?

I am running Ubuntu 12.10 and Eclipse 4.2(Juno).

You can also use jps -l to get all of the process id's of java processes
