Marcio Moraes commented on HHH-2442:
------------------------------------

The error stop after change JBoss-Cache configuration CacheLoaderShared to false.

Is it a Hibernate bug or JBoss cache bug?

> I'm getting a error when using hibernate 3.2.2.ga with cache (JBoss-Cache) cluster.
> When hibernate get a entity from second level cache it confuses the arrays of values against array of types.
> So in some situations i got ClassCastException ...

>             final Object result,
>             final Serializable id,

>             final EventSource session)
>     throws HibernateException {

>         Object[] assembledProps = TypeFactory.assemble(
>                 values,
>                 persister.getPropertyTypes(),
>                 session, result
>             );
> The issue is values (Serializeble[]) is in wrong order compared with persister.getPropertyTypes() (Type[]).
> If only one cache instance is running it doesnt occurs ...
