instance not of expected entity type: java.util.HashMap is

[talios]

I've entered this as HHH-3647 already but thought I'd also mention it here, under current trunk envers is somewhat dead as a dodo when trying to write records, I get the following stacktrace:

org.hibernate.HibernateException: instance not of expected entity type: java.util.HashMap is not a: smx3.schema3.Party_versions

Has anyone seen this behaviour before? Where the entity is a HashMap? Maybe I've missed a configuration setting thats tripping things up?

Hello,

I see you are using inheritance - do you also use Hibernate-trunk? Because the perister work-around in Envers has been removed and an appropraite fix made in Hibernate code.

We're not using hibernate trunk no, but I guess we could - really trying to get away from trunk/snapshots as much as if possible thou I don't seem to be having much luck :)

I'll update my main hibernate tree and build trunk in the morning.

Ok, hope it will work - nothing much else has change in hibernate in addition to that fix.

A snapshot of hibernate is also deployed in the JBoss Snapshots Maven2 repository, if you'd be interested.

Manager isn't really keen on running a SNAPSHOT version of hibernate unless we know the release is "soon" :(

I thought I'd just try the preview snapshot from http://www.jboss.org/envers/downloads/ sadly also throws this HashMap exception using 3.3 :(

Yeah ... a new version of Hibernate should be out in 1-2 months. But the downloadable version is just a jar compiled from trunk - so the persister bug will also be visible there, when using 3.3
