    Description

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

      Caused by: java.lang.NullPointerException
      at org.apache.openjpa.jdbc.meta.strats.RelationToManyInverseKeyFieldStrategy.map(RelationToManyInverseKeyFieldStrategy.java:136)
      at org.apache.openjpa.jdbc.meta.strats.RelationCollectionInverseKeyFieldStrategy.map(RelationCollectionInverseKeyFieldStrategy.java:95)
      at org.apache.openjpa.jdbc.meta.FieldMapping.setStrategy(FieldMapping.java:120)

      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...
