> Are you saying that without your ImprovedMappingDefaults class, everything
is working okay?
Yes. Also just checked that if I use ImprovedMappingDefaults class, but
comment out all methods so it doesn't override anything, it works fine.
> Dumb question,
are you sure your persistence.xml that has the SynchronizeMappings property
is in use?
Yes, sure :) Just double-checked with using Trace for all logging.
> You could turn on Trace and check to see if the tables are maybe being
created under a different schema, or some other processing that is
unexpected or not consistent.
In fact, tables are _not_ created at all. (I should have mentioned it
before, but I already had SQL=Trace for testing).
Looking at JUnit panel has shown something interesting. Don't know why it
wasn't present in the console output, but there is a different exception
there:
<openjpa-2.2.0-r422266:1244990 fatal user error>
org.apache.openjpa.persistence.ArgumentException: Errors encountered while
resolving metadata. See nested exceptions for details.

What's up with the last exception? Why can't it find a column in the list
which clearly includes it?
Here's the entity class, in case it helps:
