Priority increased. Deadlock in filesystems on initialization openfile
module on startup. 
OpenIDE-request-processor-0
Default RequestProcessor
Folder recognizer 
 are waiting to lock in main thread ....
main is waiting in 
at
org.openide.filesystems.MIMESupport$CachedFileObject.isAnyResolver(MIMESupport.java:138)
Comment 3 rmatous 2003-01-15 15:16:08 UTC 
I know, that P.Nejedly showed me the same dumpstack.
I don't see any reason why to wait in
MIMESupport$CachedFileObject.isAnyResolver(MIMESupport.java:138).
Strange dumpstack, I don't understand, then I'm not ready to fix.
Comment 4 rmatous 2003-01-16 16:15:18 UTC 
So, according to previous comment marked as WORKSFORME. If this
problem occures again, then this dumpstack could be send to jdk team
to analyse.

Reopened because this bug recently occured on many platforms
(SOLARIS,LINUX,WIN 2000) last week.
Comment 8 bht 2003-01-21 05:13:36 UTC 
I get this symptoms on Win98, too. Next time I will try to get a stack
dump on Win98. [Ctrl+Break] I guess.
Comment 9 pzajac 2003-01-23 09:20:00 UTC 
can you add your jdk version and platform?
It occured on linux :
 jdk 1.4.1-b01, jdk 1.4.1-b21
Comment 10 rmatous 2003-01-23 09:55:38 UTC 
Problem was that main thread waited for clinit of CachedFileObject,
that couldn't be finished because of waiting for lock. The dumpstack
was confusing.

Fixed in trunk.
