protected static Object doChooseMostSpecificParams(String theClassName, String name, List matchingMethods, Class[] arguments, boolean checkParametersCompatible) {
    long matchesDistance = -1;
    LinkedList matches = new LinkedList();
    for (Object method : matchingMethods) {
        final ParameterTypes parameterTypes = (ParameterTypes) method;
        if (checkParametersCompatible && !MetaClassHelper.parametersAreCompatible(arguments, parameterTypes.getNativeParameterTypes()))
            continue;
        long dist = MetaClassHelper.calculateParameterDistance(arguments, parameterTypes);
        if (dist == 0) return method;
        matchesDistance = handleMatches(matchesDistance, matches, method, dist);
    }

    int size = matches.size();
    if (1 == size) {
        return matches.getFirst();
    }
    if (0 == size) {
        return null;
    }

    //more than one matching method found --> ambiguous!
    throw new GroovyRuntimeException(createErrorMessageForAmbiguity(theClassName, name, arguments, matches));
