Comment 3 Martin Entlicher 2012-05-30 12:39:16 UTC 
org.openide.util.RequestProcessor$SlowItem.<init>() is slow and there's nothing we can do about it in debugger.
Probably wontfix.
Comment 4 Jaroslav Tulach 2012-06-01 22:30:55 UTC 
There is special constructor for RequestProcessor that always uses the FastItem. Possible errors are then harder to debug, but if you are posting a lot of tasks into the RP, you will see a speedup.
