Hi Andreas,

This may be https://issues.apache.org/jira/browse/DERBY-5289. You may want to build the head of the 10.8 branch and try upgrading to that version. Alternatively, you may want to wait to upgrade until 10.8.2 is published. The current schedule for 10.8.2 can be found here: http://wiki.apache.org/db-derby/DerbyTenEightTwoRelease

Hope this helps,
-Rick

Hi,

I develop an application which used derby 10.6 and now I wanted to
upgrade to 10.7.x - 10.8.1.2

but I run into following error on startup of the database (no matter
what application (my app, SQuirrel, OpenOffice base) I use, and with
all databases I could find):

Restore of a serializable or SQLData object of class , attempted to
read more data than was originally stored
 See derby log attached.. :-/

--- any suggestions if this is a bug in the newest derby driver, or
something I can rectify within my database design?

Thanks a million,

Andreas

    Hi again,

    sorry I got the wrong versions in my mind, the databases have been
    originally created using the 10.5.3 release of derby..
