Sounds reasonable. But behavior now is unfortunately even worse, neighther 

        final Properties dbProps = new Properties();
        dbProps.put("create", "true");
        dbProps.put("shutdown", "true");
        fDirectDerbyConnection = DriverManager.getConnection("jdbc:derby:" + 
dbDir, dbProps);

nor with

        fDirectDerbyConnection = DriverManager.getConnection("jdbc:derby:" + 
dbDir + ";create=true;shutdown=true");

the database get's created at all any longer. I get immediately exception 
saying that the database directory does not exist. Indeed it does not. Though 
without the shutdown parameter it then is created again. Seems as now the 
create=true is ignored in this mode.

So how do I now can force the database creation if not yet existing?
Or alternatively how do I shutdown it manually (to avoid this properties/URL
