private static int compareMethodTypes(final MethodType ownType, final MethodType otherType) {
    // Comparable interface demands that compareTo() should only return 0 if objects are equal.
    // Failing to meet this requirement causes same weight functions to replace each other in TreeSet,
    // so we go some lengths to come up with an ordering between same weight functions,
    // first falling back to parameter count and then to hash code.
    if (ownType.equals(otherType)) {
        return 0;
    }

    final int diff = weight(ownType) - weight(otherType);
    if (diff != 0) {
        return diff;
    }
    if (ownType.parameterCount() != otherType.parameterCount()) {
        return ownType.parameterCount() - otherType.parameterCount();
    }
    // We're just interested in not returning 0 here, not correct ordering
    return ownType.hashCode() - otherType.hashCode();
