Failover transport hangs on startup if it cannot connect to a broker

[Uwe Kubosch <uw...@datek.no>]

Hi all!

The failover transport should return normally on connection.start() even
if it cannot connect to a remote broker on startup, right?

In all cases I am trying, it blocks on startup, preventing
initialization of the rest of the ActiveMQ components.

I have filed a Jira issue on this: AMQ-2114

Anyone, please feel free to clarify the usage of the failover transport
in case I am missing something.  What I expect from the failover
transport is robustness regarding remote broker connection failures.

I'll look at the source and see if I can make it do what I want, and
submit a patch.  Currently the failover transport blocks on sending a
connection info message to the remote broker as part of startup, and I
think already has a mechanism to do that on reconnect.

Check out http://activemq.apache.org/failover-transport-reference.html

If it is attempting to establish a connection it will block. 

With the timeouts and such you might be able to get around start() blocking
and do your own queuing of messages because if there isn't a valid
connection the send() will throw after a timeout.
