Subject [jira] Created: (DERBY-2221) Cannot re-connect to 10.0 database after soft upgrade with 10.3 (trunk) code

Cannot re-connect to 10.0 database after soft upgrade with 10.3 (trunk) code
----------------------------------------------------------------------------

                 Key: DERBY-2221
                 URL: https://issues.apache.org/jira/browse/DERBY-2221
             Project: Derby
          Issue Type: Bug
    Affects Versions: 10.3.0.0
            Reporter: Daniel John Debrunner


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.
