Xalan not thread-safe?

Xalan not thread-safe?

2003-07-24       - By Verachten Bruno

Hi,

I've been using Xalan/Xerces for years without any noticeable problem,
but I now have to face a possible thread-safe problem.
I have a web site runned by Tomcat4, and I use the JSTL XSLT Transformation
tag.
When I stress the web site, I get a strange exception from times to times
from Xalan/Xerces.
Once this exception is thrown, I have to restart the JVM, because no other
XSLT transformation can be processed.

Can you help?

Thanks.

xalan 2.4.1 and xerces 2.3.0
