Hi Scott,

That is what I thought but if that would be the case wouldn't it be wrapped inside a 
InvocationTargetException?
I than assumed it could maybe be caused by a dynamic proxy throwing this exception.  
Yet in case of a java.lang.Error it would actually not get wrapped in a 
UndeclaredThrowableException according to javadoc and my tests.

Maybe a naïve question but, is there code in JBoss that would explicitly throw an 
UndeclaredThrowableException and stuff a "marshalled" exception inside it?

Sebastian
