I think that the patch (by accident) is actually correct here. Since 
Java permissions can be granted to code and to principals that are not 
database principals, then derby authentication being active or not is 
not relevant. E.g. when running embedded in a J2EE container the 
principals may be setup and authorized correctly by the container, thus 
not requiring any database authentication. In that case I should be able 
to grant permission to a specific set of principals to create databases 
or shutdown the system.
