I filed three Jira Issues as the result of this thread.
DERBY-4253 - documentation should indicate that a database cannot be 
upgraded if already booted in soft upgrade mode
DERBY-4254 - If upgrade is not performed when connecting with the 
upgrade=true attribute specified, Derby should produce a warning
DERBY-4255 - DatabaseMetaData getDatabaseMajorVersion() and 
getDatabaseMinorVersion() return software version rather than database 

I was going to suggest you use the DatabaseMetaData methods instead of 
the undocumented property, but found they didn't work. #:(

Thank you Evan for the useful input.
