Description Martin Entlicher 2001-11-20 14:40:33 UTC 
Not sure if it's reproducible. Happend after restart of the IDE, have 3 Generic
CVS filesystems and one local directory mounted.
Build #200111200100.
Exception attached.

Comment 2 Jesse Glick 2001-11-26 11:23:42 UTC 
FO.write should probably make a clone of 'order' before using it. Or
synchronize access to it. Looks like a race condition.
Comment 3 Jan Chalupa 2001-11-27 13:03:55 UTC 
Target milestone -> 3.3.1.

I evaluated this bug. There seems to be problem in synchronization 
between methods setOrder and findFor (both use different lock for 
synchronization - because findFor is static). Suggested patch:

Fixed in release33 (FolderOrder 1.7.14.1). Synchronization was 
changed in method findFor.
