This collector consumes an ActiveMQ 5.x queue for messages that contain a list of spans. Underneath
this uses the ActiveMQ 5.x JMS client, which has two notable dependencies slf4j-api and hawtbuf.
The message's binary data includes a list of spans. Supported encodings are the same as the http POST /spans body.
The message's binary data is a list of spans in json. The first character must be '[' (decimal 91).
Codec.JSON.writeSpans(spans) performs the correct json encoding.
Here's an example, sending a list of a single span to the zipkin queue:
$ curl -u admin:admin -X POST -s localhost:8161/api/message/zipkin?type=queue \
-H "Content-Type: application/json" \
-d '[{"traceId":"1","name":"bang","id":"2","timestamp":1470150004071068,"duration":1,"localEndpoint":{"serviceName":"flintstones"},"tags":{"lc":"bamm-bamm"}}]'
