Henning-
Do you have the "User" class listed in a <class> tag in your
persistence.xml file? Can you show us your persistence.xml file?

I tried to execute an unnamed query (using the 0.9.7 release) and got

ArgumentException: Could not locate metadata for the class using

"User".
All named queries on that same entity work fine.
All mapping is specified externally (orm.xml; no Annotations). The
Structure is very simple (no MapppedSuperClass etc.).
I lurked into your issue tracker and found this bug fixed recently.
Has
that fix gone into the 0.9.7 release?
Does it matter that my app runs in a Spring container (2.0.4)? I
got the
following stack trace
Caused by: <0.9.7-incubating fatal user error>
