Henry Zongaro updated XALANJ-1914:
----------------------------------
Description:
Using the currentCVS version of XalanJ2.
When I run transformation using single thread, it works fine.
When multi threads are using for the transformation using the same xml file and
xsl file that is used in single thread test, I get various symptoms. The
following three symptoms occur randomly:
First Symptom:
--------------
javax.xml.transform.TransformerException: 5 >= 1

These symptoms are random. Also, the output file is not consistent. In
multithread environment, the output file seems to differ for one thread to
other.
