      Description

      The example I'll attach crashes with an NPE when running the mappingtool.

      Caused by: java.lang.NullPointerException

      The goal of this JIRA is not (neccessarily) to support the kind of mapping that would be required for this (which may be hard), but to at least print a clear error and not an NPE...
