[xep-support] Null Pointer Exception

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.

Best regards,
