Subject [jira] Resolved: (DERBY-2221) Cannot re-connect to 10.0 database after soft upgrade with 10.3 (trunk) code
Date Wed, 23 May 2007 22:08:17 GMT

Mike Matrigali resolved DERBY-2221.

    Resolution: Cannot Reproduce

I believe that the upgrade tests are now running successfully against 10.3 , testing upgrade
from all previous releases.  A
number of changes went in close together to get upgrade working against 10.3 .  I  never saw
this exact stack while working
on those issues so I reported and fixed separate bugs to exactly document what I was fixing.

The bugs fixed to get the upgrade tests running in 10.3 trunk included:

> Database fails to start with 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

> setting the system property derbyTesting.jar.path to point to a folder that contains
a release in the folder
