Please raise you hand.
Otherwise we could consider this bug close by lack of fighters :)

> 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.
