[jdom-interest] JDOM8,XERCES2.3,TOMCAT4.0 Schema Validation - Class Cast Exceptio n Unkown Source Error

[Laurent Bihanic]

Hi,

Xerces 2.3.0 is broken regarding the support of the Xerces-specific schema 
validation properties (See bug #16528 at 
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=16528). This is what causes 
the error.

To work around this bug, you should stick to Xerces 2.2.1 or switch to 2.4.0 
which is said to fix the problem.
