Description

When using a Deltaspike Messagebundle and feeding null as argument to some non-String argument, the MessageInterpolators throw Exceptions. Depending if I use the MessageFormatter or the String.format based Interpolater the Exceptions differ, but origin from the same misassumption, that null can be replaced with "'null'" (MessageBundleInvocationHandler:179)
I created 2 unittests to showcase this behaviour, see attached surefire logs.
