[xep-support] Null Pointer Exception

[Rob Stote]

Thank you I can now run XEP inside of Jboss.

	I was wondering, I am getting some extremely slow processing times,
in fact I am noticing that XEP takes at least 50% more time to render a 2
page PDF document compared to FOP. I was wondering are there any performance
tuning tips you may suggest ?

The problem is due to incorrect class loader manipulations 
in JBoss: java.lang.String used by your application and java.lang.String
used to load system properties are loaded by two different loaders, and
appear as different classes. It causes problems for applications 
trying to enumerate system properties via java.util.Enumeration: you 
cannot cast obtained values to java.lang.String because the types 
don't match :-).

The problem has been already addressed in XEP 3.5.4. I suggest 
upgrading XEP to the latest version.
