I can add those synchronized back. However, findbugs will complain that so I will add rules too. On Netty side I can assure your concern: 1. In ClientCnxn, primeConnection(), cleanup(), queuePacket(). primeConnection(), cleanup() is guaranteed to be start and end of life cycles. queuePacket() is appending packets to outgoingQueue and waking up the blocking queue.
