Ubuntu: Netbeans 7.2 suddenly has CPU spikes and slows down completely


When I first installed Netbeans 7.2 everything was pretty smooth. But for the past couple of days I've noticed that after a few hours of usage the CPU usage begins to spike to unbearable levels. Forcing me to restart the application.

I haven't installed anything besides package manager updates, which I guess should be the first place to look. But I was hoping someone might also have seen this issue and would know what I should look into.


I installed NetBeans 7.2 on Ubuntu 12.04 (using .sh file downloaded from NetBenas site and Oracle JDK) and do not have this problem. Do you use OpenJDK? I may caused by OpenJDK.
