> When operating in NO_ACK mode (acquire mode pre-acquired, accept-mode none) with a 0-10
client, the retained ImplicitAcceptDispositionChangeListener objects can lead to connection
closure timeout as release() is called on the ImplicitAcceptDispositionChangeListener's and
potentially millions of log messages are generated. Additionally, the retention of these objects
for each client for each message can lead to a huge memory footprint and result in OOM Exceptions.
