I have a PersistenceManager
PersistenceManager pm = PMF.get().getPersistenceManager();
which I use to do a bunch of operations on different objects, but
WITHOUT transaction (run queries, store entities and lookup entities).
I then close the manager with pm.close() and get this obscure error
that complains about multiple entity groups inside a transaction even
though I am not using a transaction (you will notice that the error is
not the usual one where it prints the different entity groups).
I am not 100% confident but have the impression that this error
started happening with the 1.3.4 release.
100% reproducible use case. Would appreciate input from App Engine
developers.
