Hi all,

okay, I found the bastard that was causing all this trouble and almost 
made me believe Java as a whole isn't mature ;)

Berin was right, the VM got killed due to the complex interaction of 
Batik while generating images; the reason seems to be a concurrency 
issue in Suns sun.awt.image.codec.JPEGImageEncoderImpl.writeJPEGStream() 
function. If multiple users access dynamically generated images and a 
user disconnects while the image is being streamed, the VM blows in Suns 
JDK1.3.1, JDK1.4beta and in IBMs JDK1.3; at least the IBM implementation 
writes a proper dump file that contains useful information.

Best regards,
