Message Title

When running a prototype benchmark integrating WildFly 12 with ORM 5.3.0.CR2 we got the following exception:

java.lang.IllegalArgumentException: org/something/bla/bla/BuyerPortType contains the illegal character '/'

Looks like WildFly is doing something odd - not sure if we should fix this in WildFly rather than ORM - but it's probably easier in terms of compatibility if we can easily be more lenient.
