JBossWS: java.lang.reflect.InvocationTargetException: Method invocation failed with exception: null

Issue

We have clients what do consume web services. These web services, when is the case, throw
"logical" exceptions what do come from our business logic. As soon as a such exception is
thrown we get another error from the web service layer (see the stack below).

Is this a known issue? Do you have a solution or patch for it?
