Sorry, I am wrong.
I inspected my source code and found the real cause.
The following code can works on SDK1.3.0, but it throws
"java.lang.IllegalArgumentException:
can't operate on multiple entity groups in a single transaction."
when it used on SDK1.3.1.
----
PersistenceManager pm = pmfInstance.getPersistenceManager();
pm.makePersistent(new EntityB("key")); // If this two lines are
commented out,
pm.getObjectById(EntityB.class, "key"); // the following code throws
exception on SDK1.3.0 too.
ArrayList<EntityA> entities = new ArrayList<EntityA>(2);
entities.add(new EntityA());
entities.add(new EntityA());
Transaction tx = pm.currentTransaction();
tx.begin();
pm.makePersistentAll(entities); // it throws exception if it compiled
using sdk1.3.1.
tx.commit();
----
Full source code is here.
