Hi Dave,
I've never seen this error.
I'd probably focus on the connection setup. What are you using for
connection pooling, and how are you configuring OpenJPA for
connections? There are several connection "options" in OpenJPA that
might help. My favorite is <property
name="openjpa.ConnectionRetainMode" value="transaction"/> but there
are others...

I'm tired of banging my head against this problem, so I'm reaching out
for help...
The Maven build works fine on Mac, but under Windows XP the build
fails during testing. The build starts Derby, creates tables and then
runs a bunch of tests. At some point, the tests start failing with an
exception of type java.net.BindException (see below). It's like
OpenJPA or the Derby client somehow lose the connection to Derby.
I have no idea if this is an OpenJPA bug, a Derby problem or a result
of some sin we are committing in the Roller tests/build process. If I
remove the test that is failing, then some other test will fail with
the same problem, so I don't think the problem is specific to one
test.
Any ideas from the OpenJPA or Derby experts out there? What types of
problems would lead to a bind exception on the client-side? What
should I do to debug this?
Thanks,
Dave

Log:
Fixes to make more of the Maven build work on Windows XP.
Currently, at least on my machine, the build fails while running
weblogger-business tests. After the bind exception below all tests
fail. Maybe we are hitting some weird OpenJPA or Derby Client bug?
