Public bug reported:

Drizzle JDBC always  MySQLServerCapabilities.CONNECT_WITH_DB flag, even
if database name is not given

Looking at the code in MySQLProtocol.java, it was not intended

            // If a database is given, but createDB is not defined or is false,            
           // then just try to connect to the given database            
           if (this.database != null && !createDB()) 
                 capabilities.add(MySQLServerCapabilities.CONNECT_WITH_DB);

However this.database is never null, it is set to  an empty string prior
to this code.

This broke Tungsten with MariaDB in recent MariaDBs :
https://bugs.launchpad.net/maria/+bug/904097 .

MariaDB happened to interpret protocol a bit stricter than MySQL (s.
