private static void modifyInterpreter(final NaturalLanguageStrategyLexer l) {
    final int originalSize = l.getInterpreter().decisionToDFA.length;
    final DFA[] emptyDFA = new DFA[originalSize]; // give our own array so the static one isn't used
    final LexerATNSimulator newInterpreter = new LexerATNSimulator(l, l.getATN(), emptyDFA,
            new PredictionContextCache());
    newInterpreter.clearDFA(); // initialize our array so that the lexer functions properly
    l.setInterpreter(newInterpreter); // replace the interpreter to bypass all static caches
}
