Hi, Has anyone meet similar problem (NullPointerException is thrown in hashCode() function) when a un-matured persistent object is added to map or set that will invoke the persistent object's hashCode() function. The execption happens because the peristent object is un-matured, that is, some of its fields is not yet deserialized from database and their values are null and the hashCode() function depends on these values to calculate the hash, hence NullPointerException is thrown. One workaround to this problem is not to implement hashCode() function in your persistent object, but does not make sense. It is observed that three places cause this problem:
1. ManageableHashSet's method ojbAdd(Object) 2. AnonymousPersistentField's method set(Object obj, Object value) 3. LoadedObjectsRegistry's method register(Object object) I am trying to figure out a solution for the latter two places. But for the first place, seems no solution yet.
