I sometimes encounter a freezing Eclipse when I apply a refactoring or quickfix (e.g., rename, extract method, create local variable / field) after the refactoring is executed, but while displaying the corresponding linked mode. Here's the stack trace:

org.eclipse.swt.SWTException: Widget is disposed                                                                        >---at org.eclipse.swt.SWT.error(SWT.java:4282)

Reproducible: Sometimes

Steps to Reproduce:
1.Missing object field member
2.Apply quick fix "create field"
3.Eclipse freezes

Did you get an exception (the stack trace look like this)? Could you take a VM dump while it is freezing?

This is a duplicate of bug 354842. I expect that you see similar freezes with other hovers and tooltips as well.

Please also try the workaround mentioned in bug 354842 comment 2.

I tried the workaround mentioned in bug 354842 comment 2 (disabling animations). But this did not make any difference for me! The problem still occurs.
