After a frustrating time building a test project to isolate what I thought was a
new issue, I discovered that there was nothing wrong with my project, I had just
forgotten to add one entity class to the PCEnhancer command during my
build-time enhancement routine.
So the class was unenhanced.
With RuntimeUnenhancedClasses set to unsupported, instead of receiving a "cannot
run with unenhanced classes" error, OpenJPA threw the exceptions below.
I think this definitely qualifies as a bug - OpenJPA is throwing the wrong
exception. It definitely misled me for a while.
Shall I open a JIRA for it?

Following on from my initial response, I copied the superclass into the

It looks like I'm taking the scenic route around all the OpenJPA issues
right now.
I hit this problem with enhanced files that doesn't happen with the
unenhanced.
I carefully set the property
openjpa.RuntimeUnenhancedClasses=unsupported so I can be certain I am
running with the enhanced classes.
So with build-time enhancement, I get stacktraces of exceptions as
follows, although it's not clear which is the original cause:

I figure that the "no registered metadata for type ..." must be the
original since it appears first and last. It runs fine unenhanced, so
what can it be? Do enhanced entities only work with annotations? These
entities are all mapped via xml.
