Hi,
just encountered, that one gets an NPE in
org.hibernate.engine.CollectionLoadContext#addCollectionToCache()
when running the legacy.FumTest#testUnflushedSessionSerialization
with MySQLInnoDBDialect + DefaultHibernateCache:
The ctx lines are:
s = getSessions().openSession();
s.setFlushMode(FlushMode.NEVER);
--> fum = (Fum) s.load( Fum.class, fum.getId() );
assertTrue("the Fum.friends did not get saved", fum.getFriends().size() == 2);
When loading is done, the correct result gets fetched from the db,
but it seems, that something goes wrong wrt. caching. I fixed, but
I'm not sure, whether it is the right thing, to do it this way...
Any opinions?
Regards,
jens.
fix:
