Closing a JDBC connection is not the same as shutting down the Derby system:
http://db.apache.org/derby/docs/10.4/devguide/tdevdvlp20349.html

         "If the application that started the embedded Derby quits but
          leaves the JVM running, Derby continues to run and is available
          for database connections."

What happens if you re-try your test, but fully shut down the Derby system?

thanks,
