> An ArrayIndexOutOfBoundsException is being thrown by
> ClassMetaData.getExtraFieldDataIndex()
> I am providing a test case. The only thing special is that the entities are
> set up in a hexagon shape, where the entities above have a OneToMany
> relationship with those below. The one at the very bottom has ManyToOne
> relationships with the two entities above it and I think this seems to be the
> cause of the problem.
> I have done some debugging on this and here is where I have gotten to:
> The problem is somewhere around the JDBCStoreManager.initializeState method
> first time through, the mapping object is
> org.apache.openjpa.persistence.jdbc.query.HexagonBottom and the
> mappedByFieldMapping is
> org.apache.openjpa.persistence.jdbc.query.HexagonBottom.lowerLeftId (looks
> good), index is 6
> second time through, the mapping object is
> org.apache.openjpa.persistence.jdbc.query.HexagonLowerRight and the
> mappedByFieldMapping is still
> org.apache.openjpa.persistence.jdbc.query.HexagonBottom.lowerLeftId, so the
> index is still 6, but the HexagonLowerRight object only has 4 fields in it so
> the exception is thrown.
