My tests pass when run in Eclipse. However, when I run them in Ant I see
errors like this:

Another instance of Derby may have already booted the database C:\Documents
and Settings\eharold\workspace\foo\build\CentralConfig.db.

ERROR XSDB6: Another instance of Derby may have already booted the database
C:\Documents and Settings\eharold\workspace\foo\build\CentralConfig.db.

Apparently one VM is creating the DB, but not unlocking it before the next
VM tries to read from it.

Surprisingly changing from <junit fork="yes"> to <junit fork="no"> does not
seem to fix this.

Any suggestions? Is there anything short of setting up a network server that
will allow my unit tests to access the same database?
