I do something like that now:
    public class SQLite3 extends SQL {
        // ################ main
        public static void main(final String[] args) throws SQLException {
            SQL.mainWork(SQLite3.class.getCanonicalName(), args);
        }

The ‘problem’ is that I have to write it for every concrete class, but
that is doable.

I renamed main in the abstract class SQL to mainWork and removed
public.
