Hi ALL

 

We have a web application which uses Xalan 2.7.0, Xerces 2.7.1 and FOP
0.94 to do transformations to HTML, PDF and CSV.  However, after
recently upgrading to these libraries we have been getting the following
exception. This is a rare bug probably in the Xerces jar that keeps on
reappearing. We can't update to the lastest Xerces version due the the
amount of testing involved and since FOP is recommended to work with
these supporting jars.

We have a fix for the problem with the same exception message
(java.lang.ArrayIndexOutOfBoundsException: 2048) but having a different
stack trace. We are able to replicate this using a standalone program
which is included as an attachment.

 

Can anyone provide us with a standalone program that is able to
replicate the above problem with the exact same stack trace? It would be
a great Help 

 

Thanks and regards
