> When querying for a class which contains a self-reference and a Map whose values contain a composite primary key, a null identifier exception is thrown.  It seems to be somehow related to the variable name because when I change MyEntity.secConfigs to MyEntity.ecConfigs and change the setters/getters appropriately, the problem no longer exists.  I believe the problem is also related to the composite primary key for ContainedEntity because when I change it to use an auto-generated long the problem also goes away.
