Client may hang during initial connection #65
There was an issue reported to Lyra that seems to have more to do with the rabbitmq-java-client. Basically the problem is that when rabbitmq connections are proxied through an AWS elastic load balancer, ELB might accept a TCP connection but not respond to the initial handshake which leaves the client hanging forever. ELB may even close the connection, but I believe the BlockingCell is just left waiting forever. Here's a call stack from a mocked up test that reproduces this scenario:
The first idea that comes to my mind is that everything that happens inside AMQConnection.start() should be covered by the connection timeout setting and/or an eventual connection closure should unblock the BlockingCell.
