> The heartbeat controls/defaults offered by the 0-10 Java client are different
> and to those used by the 0-8..0-9-1. This has the potential to confuse the
> end-user and makes clear documentation more difficult.
> The current situation looks like this:
> The 0-10 codepath defaults heart-beating to enabled with a period of 120s.
> It may be configured on the client side by either:
> * broker url option ?heartbeat=... (value in secs)
> * system properties qpid.heartbeat (value in secs), amqj.heartbeat.delay
> (secs), idle_timeout (ms). The latter two are considered deprecated.
> The 0-8..0-9-1 codepath defaults heart-beating to disabled. It may be
> enabled on the client side using the system property amqj.heartbeat.delay.
> In the Java Broker's implementation of 0-8..0-9-1 allows heartbeating to be
> enabled from the server side, by a mechanism where the server proposes a
> heartbeat value to the client, and the client can either accept the value or
> put forward its own. The client does not understand the broker url option
> 'heartbeat' nor the newer system property qpid.heartbeat.
> The Programming in Apache Qpid docbook reflects the 0-10 behaviour and makes
> no mention to the differences in the other protocols.
> The intention is to change the code as follows:
> # make both code paths understand the qpid.heartbeat system property.
> amqj.heartbeat.delay will continue to be supported as deprecated.
> # make the broker url option heartbeat=... will be understood by both code
> paths
> # update docbook
