      Description

      We have the NPE shown below in a reproducible testcase (ZIP attached to JIRA ...).

      We've reduced our complex intended target domain model (about 200+ Entities) to a simpler model with only 3 classes which illustrate the problem: You'll find attached a test project with a first entity which has a a OneToMany (with an ElementJoinColumns, but that shouldn't matter?) to a second entity has a ManyToOne to a third entity. The middle entity has a Composite ID Class including a ManyToOne as a key, which according to http://openjpa.apache.org/builds/1.2.0/apache-openjpa-1.2.0/docs/manual/ref_guide_pc_oid.html#ref_guide_pc_oid_entitypk is supported, so this seems a bug in OpenJPA's mapping algos, somehow?
