PLEASE DISREGARD.

Description: 
I added a couple of help files to the filesystem and then quit and tried to 
relaunch single user and multiuser. The first few times it just hung, but I 
finally got it to come up I got these two exceptions. (Build 1018 on Solaris 
JDK 1.2.2_05a). See comments for full command shell output

Public Summary: 
The bug is marked not reproductible (or maybe obsoleted) for now, waiting for 
reaction of reporter.

Evaluation: 
I did not succeeded to reproduce the bug at all. I tried both with builds 1018 
and 1085 (new one). I need more information to resolve this bug. Please, try to 
reproduce this bug using newest build to see if it is not obsoleted.
In a case you will succeed to reproduce with new build, please specify *exact* 
steps. From your previous description,I don't know what does it mean 'add a 
help file to filesystems'...did you mount help file somehow? or did you copy 
some help files to the directory shown in filesystems? which files? etc...

Thanx a lot.

Dafe
