The error message about upgrade from 10.1 to 10.2 beta indicates that 
the user is trying to access a database created with an official release 
(10.1) with alpha/beta software.  This is by default prevented in order 
to avoid that a production database is accidentally corrupted by 
unstable software.  It is possible to allow this by setting the property 
derby.database.allowPreReleaseUpgrade.  However,10.2.0.3 is an alpha 
release that came with an early access release of JDK 6 (build 89), and 
I think the user should consider to use a newer version of Derby (and 
the JDK?).

Hope this helps,
