Description David Koski 2006-04-14 18:13:41 EDT

After using eclipse for a few hours to edit java code (nothing fancy, just using the editor, no plugins used that I know of), it will start chewing up 100% CPU.  This is on Mac OSX 10.4.6.  I have 3G of RAM and gave -Xmx768m.  Looking at the gc logs, there is nothing abnormal going on there and it is still at the -Xms size.

I noticed that I don't even have to be doing anything other than moving the mouse around over the text area of the window.  Here is a thread dump while it is sucking up cpu:
