You might want to try one of the javax.jdo.PersistenceManager.getObjectsById(...)
methods. I have not done this myself yet (although I do use getObjectById(...)), so I have not used an array or collection of OIDs. You might want to give this a try. Failing that, you might want to have as an instance of each ManyToManyLink not a key for Entity1 and Entity2 but instead a key for one entity and an array list of keys for the other entity type, so your original query will return an array list of keys.
