- It appears that the callable query hint (org.hibernate.callable) cannot be set on a native query (not a named native query, a regular native query).
- I scoured through the source and the SQLQueryImpl constructors do not support passing in a callable parameter except if it is a named native query.

So if I am excuting a stored proc (which doesn't match to an entity very nicely) it will often not work. the setHint() call via JPA is of no value in this case.


Seems like a bug to me?

note:
the only other constructor that allows the passing of a callable value is marked with the comment:


kind of funny, I need to use that overridden constructor!

I found something similar. Seems SP not well supported.
