Comment 1 Olivier Thomann CLA 2002-02-04 14:06:08 EST 
Could you please give us mnore details about the source you saved?
What is your build number?
Without this information it is quite difficult to track down the problem.
Thanks for the report.
Comment 2 Kirill Frolov CLA 2002-02-06 02:29:55 EST 
Build is 20020125 (latest stable)
The file I was edited was quite large (above 50k) and it was 
quite ordinary Java source file. Particularly the implementation class for entity ejb if it 
matters. I repeat, the file was very ordinary. And this exception has never been fired before or 
after. Maybe the reason why it fired - the exact modifications I made... I don't have any idea. 
Well, actually, I don't think it's worth fixing now (if the reason is not obvious to you).
Comment 3 Olivier Thomann CLA 2002-02-06 13:56:39 EST 
I don't understand how the NPE is possible. I added a protective null check on the guilty 
line.
Fixed and released in HEAD.
