Comment 1 Marian Mirilovic 2002-10-23 15:58:00 UTC 
Removing modules? Do you mean disbaling or removing jars from
<netbeanshome>/modules?

What do you exact did? Build number, JDK ...... .
Comment 2 pzajac 2002-10-23 17:18:09 UTC 
Marian, description contains dev build 200210150100. This bug doesn't
seem like jdk dependend.
Comment 3 _ gtzabari 2002-10-24 03:20:11 UTC 
By "removing modules" I meant unloading them using OPTIONS | SETUP
Comment 4 pzajac 2002-11-25 15:41:58 UTC 
It seems as problem in InheritanceTree.Node.chilren ArrayList of Nodes
but I don't see any synchronization problem.
Comment 5 pzajac 2003-02-18 10:27:00 UTC 
We cannot to reproduce this bug. There were many changes in
FolderLookup and AbstractLookup. Reopen it if the exception occured again.
Comment 6 Marian Mirilovic 2003-07-31 10:26:52 UTC 
Without new informations for long time - verifying.
