Comment 1 Jan Pokorsky 2008-09-30 09:40:00 UTC 
Could you attach also stack trace of the test? It would help to know what refactoring operation breaks it in
testProjectsView.
There is a pretty complicated threading model in ParametersPanel which I would like to rewrite but not now before 6.5.
release.
Comment 2 Jan Pokorsky 2008-09-30 09:53:41 UTC 
I guess I got it. I already fixed it with http://hg.netbeans.org/main/rev/e624b1492218 yesterday. And here is the stack
trace of the test:

org.netbeans.jemmy.TimeoutExpiredException: Wait "Closed window" state to be reached

User Comments: 
I tried to rename a servlet: right clicked in Projects window on a servlet selected Refactor->Rename. Provided new name and marked to change also comments. Then I hit OK and exception was thrown. Nothing changed, servlet name was the same, web.xml was not updated etc.

No reports in 6.9. Probably fixed.
