In fact if I back out that commit, the IDE starts fine - but just tried it once.
Comment 2 Jan Peska 2011-10-13 14:19:46 UTC 
I reverted the patch until I will find a solution for this freeze.

fixed Patch - please review

Original patch was part of the fix from http://netbeans.org/bugzilla/show_bug.cgi?id=202432

Sometimes happened that TimableEventQueue perform wait cursor check before RunOffEDTImpl.runOffEventDispatchThreadImpl set wait cursor even though time for setting wait cursor was set to 50 ms and time for wait cursor check was set to 100 ms. Slowness report was displayed but did not have to be.

I wanted to fix this with performing another wait cursor check after REPORT time (set in TimableEventQueue.java)

It seems I've resolved this freeze issue (don't know why it does not trigger during my tests) and I would like to ask you if you could review it to avoid further inconveniences.

Thanks
Comment 4 Jesse Glick 2011-10-13 21:05:54 UTC 
The freeze was fixed by reverting the bad change, yes? So it is bug #202432 which is now open and to which further comments should be addressed.

As to reviewing an alternate fix, I am afraid I know little about this class so you will need to find someone else if you want advice.
