Invalid version: 6, could not load org.apache.activemq.openwire.v6.MarshallerFactory

Really excited to try out an amq command line tool but running into a problem. We have ActiveMQ 5.4.x in production. Is there a minimum version of ActiveMQ that is supported? Here's the error:

I'm on Java 8:

[root@ewhserver1512 amqclient]# /usr/bin/java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

And ActiveMQ is definitely running - this is not a new install - as my app uses it successfully (with the localhost:61616 url).

Appreciate your help and happy to provide any additional data if necessary.

Support for very old ActiveMQ versions require a specific legacy dependency. I will include it in the next release.

[Petter Nordlander]

Just released v1.4.4 with this feature enabled.

Thanks for the add and the awesome turnaround!

Just tested and verified I can now connect locally. Thanks again @northlander.
