Kevin-
Weird. From the error message, it looks like there is some problem
with deserializing the default model from the companies.xml file from
the XMLDecoder.
I've put some extra debugging logic in the CompanyModelTest.java that
should throw a better error when the deserialization fails. Can you
update and re-run the test and let us know if the stack trace changes?

Hi,
After synching up with the latest changes in SVN, I am hitting an

To prevent this connection in the future, set your

They seem to most often happen when I do a complete top-down build
from the
openjpa directory (mvn clean && mvn install) and let it traverse the
sub-projects. This is from the command line (not Eclipse).
I can immediately turn around and do a "mvn test" from the openjpa
directory
and everything tests out just fine.
Any ideas on what is causing these type of errors? I don't see
anywhere in
our code where we are producing these type of messages. I'm not
sure if
it's related to one of our dependencies (serp?), or maybe it's
another IBM
JDK anomaly (haven't been able to reproduce with Sun yet, but it is an
intermittent problem).
Thanks,
Kevin
