Comment 2 Marian Mirilovic 2010-09-08 07:52:07 UTC 
reproduced on Ubuntu, started with an empty userdir and created new Java project -> IDE hangs
Comment 3 Vladimir Voskresensky 2010-09-08 08:19:16 UTC 
reproduced on Solaris.
Just start IDE (no ergonomics) with fresh userdir => "Opening Main Window..." never finishes, IDE is frozen

Looks like P0 (zero)...

probably related issue #190229
Comment 5 Stanislav Aubrecht 2010-09-08 08:57:30 UTC 
reproduced on windows as well. reverting the fix for #190176 solves the problem

reassigning

Comment 8 David Konecny 2010-09-09 01:44:44 UTC 
P4 bug fix in data systems (issue 190176) made the IDE completely unusable - basically IDE never starts again. Changing synchronization in error-prone and hard to maintain code like Data System without testing is reckless. And despite our build infrastructure the problem spreads through all team repositories and everybody is impacted.

I would probably suggest to stay away from DataSystem and fix only priority issues there.
Comment 9 Jaroslav Tulach 2010-09-09 08:13:42 UTC 
I'd like to apologize for causing one day instability in NetBeans builds.

The problems spread around as we no longer run any part of UI validation during the sanity tests.

In contrast to other parts of NetBeans code base, the P4 bug 190176 was the highest open priority bug in openide.loaders. Causing regression is indeed unfortunate, but unless it affects stability of 6.10 release, it is not a reason to give up: 1482ef3b369d
