      The null pointers look like the result of stuff going on while the system is doing a hard shutdown because it encountered an checksum error,
      I'll attach a full derby.log - but here is the stack of interest.

      ------------ END SHUTDOWN ERROR STACK -------------

      This test passed in many other environments against this build, so my assumption is that this is intermittent. I have not seen this issue in this test before.
