JMS Map Message Should Support AMQP 0-10 Encoded Map As Message Body
--------------------------------------------------------------------

                 Key: QPID-2363
                 URL: https://issues.apache.org/jira/browse/QPID-2363
             Project: Qpid
          Issue Type: New Feature
          Components: Interop Testing, Java Client
            Reporter: Rajith Attapattu
            Assignee: Rajith Attapattu
             Fix For: 0.7


As part of the new API initiative in Qpid, the C++ client and python client 
have added support for a map message, where the content is a map of key,value 
pairs encoded using the AMQP 0-10 encoding for Maps.
Currently the JMS Map message body is encoded as an opaque binary blob. 
We need to add support for the JMS Map message implementation to set an AMQP 
0-10 encoded Map for the message body. 
This allows inteoperability btw JMS Map messages and c++, python map messages.
The content-type for the proposed map message is "amqp/map".

This feature is only added to the 0-10 code path as the versions below AMQP 
0-10 does not have any native support for encoding maps.
The new map message format will be the default for any map message created by a 
0-10 Session.
If it needs to send any messages using the old map message format it will need 
to use the following jvm arg "-Dqpid.use_legacy_map_message=true"
Once the addressing support is finalized we could also add a per destination 
flag to indicate if legacy messages needs to be used or not.
