Hi Oliver,

I didnt find why it should be supported outside criteria API:

{code}
The semantics of this method may be extended in a future release of this specification to support other result types. Applications
that specify other result types (e.g., Tuple.class) will not be portable.
{code}

annotates createQuery()

> This breaks at {{result.get(0)}} with {{java.lang.ClassCastException: java.lang.String cannot be cast to javax.persistence.Tuple}}.
