'Eclipse freezes on suggestion popup

I am having a problem in Eclipse where it freezes whenever I add a period (to try to bring up the content assist popup with possible methods). I can move the mouse, but the blinking text cursor disappears, I can't switch tabs or save, and I need to use a task manager to close Eclipse. This happens with all Java projects/files.

I have never had a problem like this with Eclipse before, and can't tell what started it. After doing several Google searches, all I found was this bug. However, I don't see a solution and am running Windows 7, not Linux. Also, I have never heard of Xulrunner. Does anybody have a solution or explanation? Is it an Eclipse setting, or a problem with my computer?

Error Log: https://dl.dropboxusercontent.com/u/101364250/eclipse_freeze.log When I watched the error view, it seemed to output "Unhandled event loop exception" a lot.

For now, I have disabled the content assist, which seems to fix the problem. However, this feature is very helpful, so any answers are appreciated!
