Comment 1 rmatous 2003-03-24 13:56:56 UTC 
Not able to reproduce according to given steps. 
Sun ONE Studio 5, Standard edition (Build 030321_1) on  j2sdk1.4.1
(Win2000). Are you able to reproduce ?
Comment 2 Jan Chalupa 2003-03-24 15:30:18 UTC 
Unable to reproduce using the provided steps on Win NT 4 SP6, Sun JDK
1.4.1_02 with build #030323.

Lark, can you reproduce this reliably?
Comment 3 Jan Chalupa 2003-03-24 16:48:06 UTC 
Tried the same on Windows XP. No exception was thrown.
Comment 4 Marian Mirilovic 2003-03-25 11:36:35 UTC 
Lark, 
we need your help: 
Is it 100% reproducible?
What do you mean by "default filesystem" ? Is "AboutExamples" the
"default filesystem"?

Thanks in advance.
Comment 5 Lark Fitzgerald 2003-03-25 18:41:14 UTC 
Sorry for the delay - I was not here yesterday.
"AboutExamples" is the default filesystem that I am referring to.
The exception happened to me on a first start after installing only. 
If I remove the userdir and restart I did not get the exception again,
so I have not been able to reproduce the problem.
Comment 6 Lark Fitzgerald 2003-03-25 19:30:56 UTC 
I am unable to reproduce this with today's kit.  It was either a fluke
last time or the problem got fixed as a result of something else. 
Closing.
