After some analysis it turns out that they compare apples with oranges :-( Inside "tryAPermutationOfRules" the rule is called with rules.get() and the next step is calling rule.compare(), but they don't compare the nodes against the rule (or rules). They compare the nodes against each other.
E.g. server1:8983, server2:7574, server1:7574,... What do you think will happen if comparing server1:8983 against server2:7574 (and so on)??? It will _NEVER_ match!!!
