Any ideas, why ?

ressigned to openide/loaders
Comment 2 David Konecny 2003-08-11 12:11:56 UTC 
Exception is strange. Is it reproducible? Does it happen always?

Petr, is the problem in NB or in Java?
Comment 3 Petr Nejedly 2003-08-11 14:27:45 UTC 
Strange enough.
One generated class trying to load another generated class, but that
should be no problem.
Unfortunately I can't inspect the sources where the exception occur
as they are generated. You can try reading the generator source...

Probably the only theoretical way how can NB cause the bug is
asynchronous playing with Thread.currentClassLoader.

BTW: Which JDK it was? 1.4.1?
Comment 4 David Konecny 2003-08-12 13:53:45 UTC 
If there is reproducible case or you have more info which could help
us to resolve it then please reopen.
Comment 5 Petr Nejedly 2003-08-15 12:45:41 UTC 
BTW: Jesse, can this be affected by NB setting currentClassLoader?
(It happened during the startup)
Comment 6 Jesse Glick 2003-08-15 16:07:54 UTC 
I have no idea if Thread.contextClassLoader (not currentClassLoader as
you wrote BTW) could be involved.
Comment 7 Marian Mirilovic 2003-09-03 15:19:45 UTC 
Without new informations - verifying.
Comment 8 Marian Mirilovic 2004-03-24 19:43:26 UTC 
reopen - duplicate
