Updated to work with the new jackson. There is an outstanding FIXME
with the AMQPBusEventAdapter.java which needs the upstream ca cert.
Before we only had the one, we how have a directory. Need to decide
if this is still needed or if we need to send the entire list.
migrate to qpid proton to support AMQP 1.0
add proton-api
bind by name to Function
use json Event instead of transformation
remove AMQPBusEventAdapter
log the type of event going through publisher
fix checkstyle
move the stop to the close() method
log when registering listeners at startup
removed whitespace
