AutorecoveringConnection doesn't use all hostnames provided to ConnectionFactory

[michaelklishin]

Looks like we have a twin brother bug to rabbitmq/rabbitmq-dotnet-client#153 in this client. Interesting that it hasn't been previously reported: perhaps many route client connections through a proxy in front of cluster.

Actually, I am wrong: autorecovering connections use
https://github.com/rabbitmq/rabbitmq-java-client/blob/master/src/main/java/com/rabbitmq/client/impl/recovery/RecoveryAwareAMQConnectionFactory.java#L30.

Need to investigate in the morning.

I can reproduce this, seems legit.

OK, some more findings:

• Current shuffling still can hit the same endpoint but should continue iterating unless it can successfully connect.
• Empirical observations suggest that the version in stable is less likely to hit it several times in a row, although I cannot rationally explain it.

We need to ask the person who reported it.
