Mike Matrigali updated DERBY-2221:
----------------------------------

    Component/s: SQL
                 Regression Test Failure

I am not seeing this issue.  Currently (on truck as of change 535573) I only see DERBY-2612 which is not a null pointer error.

> Database fails to start with 10.0.2.1 after a 10.3 database has connected to it. Caused by a NullPointerException.
> Even if 10.0 is not a common starting point it would be good to track down what is causing this, it seems to be some on-disk format
> of an object has changed in an incompatible way.
> To reproduce run the JUnit upgrade test added by DERBY-2217
> org.apache.derbyTesting.functionTests.tests.upgradeTests._Suite 
> setting the system property derbyTesting.jar.path to point to a folder that contains a 10.0.2.1 release in the folder 10.0.2.1.
