This revision:

http://hg.netbeans.org/core-main/rev/e581cbb703c0

Results in a hang in "done()" on the line "WAIT_CURSOR_CHECKER.waitFinished();". The NetBeans UI never loads - just sitting at a white screen.

Jardo, can you please review this patch?

Thanks

Another WAIT_CURSOR check added after REPORT time
Comment 15 Jaroslav Tulach 2011-10-19 17:55:17 UTC 
create(..., true) is good idea. Also consider:

if (!WAIT_CURSOR_CHECKER.cancel()) {
  WAIT_CURSOR_CHECKER.waitFinished();
}

as true from cancel should mean the task has not even started.

Sounds reasonable. I'm going to test it.
