To be forward-compatable with the next version of ECJ, you should write

        String alphabet = state.parameters.getStringWithDefault(
                p, null, "aAbBcCdDeEfFgG");

Only if MyProblem specified the parameter name that way, one of:

        new Parameter("eval.problem.alphabet");
        new Parameter("eval").push("problem").push("alphabet");
        base.push("alphabet");  // assuming base passed in was "eval.problem"

Absolutely.  In reset() you could write:

        new Parameter("eval.problem.alphabet");

Or if you'd like to just use "alphabet" as your parameter, in MyProblem
you can just ignore the base and do:

        new Parameter("alphabet");

Keep in mind that the ONLY function of parameter bases is to provide a
way of handling name-spacing.  In fact you can specify whatever the
heck parameter names you'd like.
