> 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 ...
> Looking up CacheEntry code at assemble method i saw:
>   private static Object[] assemble(
>         final Serializable[] values,
>         final Object result,
>         final Serializable id,
>         final EntityPersister persister,
>         final Interceptor interceptor,
>         final EventSource session)
>   throws HibernateException {
>      //assembled state gets put in a new array (we read from cache by value!)
>      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 ...
> I am using Linux.
