Comment 1 mslama 2006-09-05 16:09:01 UTC 
Confirmed with daily dev NB 6.0 build 200609041800.
Dispatching to welcome module. Steps to reproduce:
1.Start IDE with fresh user dir.
2.Exit IDE.
3.Start IDE.
4.Disable welcome module in Module Manager -> Help
5.Exit IDE.
6.Start IDE -> Exception. Different from exception given by Tim. This time it
fails when initializing lookup during startup.

It is important to follow given steps. There is no problem when you disable
welcome module during first IDE session. It seems there is problem with cache.
Jarda is it possible to clean cache when module is disabled or handle this by
some other way?

Comment 3 Stanislav Aubrecht 2006-09-12 14:05:17 UTC 
i fixed the welcome screen not to use SystemOption any more. but there clearly
is an issue in the module system - reassigning to openide for evaluation
Comment 4 Jesse Glick 2006-09-12 14:20:12 UTC 
No one knows how to reproduce Tim's exception. In fact it is from
javac-generated code, not NB source code: the inner class' outer class field is
null?!

Marek's exception is to be expected if the .settings file fails to declare which
<module> it is from.

Primary problem fixed -> P4 for possible investigation or closing.
Comment 5 Antonin Nebuzelsky 2008-04-15 17:12:41 UTC 
Reassigning to new module owner jskrivanek.
Comment 6 Petr Chytil 2008-09-02 14:31:46 UTC 
Without requested information for long time - INVALID. We can't do anything in this case, so please reporter add
requested information and reopen issue. Thanks in advance.
