Subject Re: 5.3 question and server upgrade question...
Date Mon, 04 Nov 2013 23:37:17 GMT
The clients should negotiate the correct open-wire (protocol version)
so in theory the broker will be backward compatible with older
clients. Just make sure the activemq-openwire-legacy jar is on the
classpath (should be by default).

Of course I would test this out to make sure :)
