Subject: [OASIS Issue Tracker] (AMQPBINDMAP-15) update handling of correlation ID for interop


    [ https://issues.oasis-open.org/browse/AMQPBINDMAP-15?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=62952#comment-62952 ]

-------------------------------------------------------------------

Consider the following scenario:
o JMS client [JMS]
o AMQP client [AMQP]

and the following steps:
1. [AMQP] sends message #1 with correlation-id 'my-non-prefixed-string-id'
2. [JMS] receives message #1 with synthesized JMSCorrelationID "ID:AMQP_STRING:my-non-prefixed-string-id"
3. [JMS] sends message #2 with same JMSCorrelationID "ID:AMQP_STRING:my-non-prefixed-string-id"
4. [AMQP] receives message #2 with correlation-id 'my-non-prefixed-string-id' ?

Just wanted to confirm that step 4 follows from the transformation rules you outlined above and that the synthesis is always reversible.

> An issue with interop between JMS and non-JMS clients when using correlation ID values on messages.
> If a JMS application sets JMSCorrelationID on a Message, it can do so either using a JMSMessageID value (a String beginning with "ID:") or an application-specific string value. Previously we decided that the "ID:" prefix of a JMSMessageID should not be sent on the wire so other non-JMS client need not deal with it, and a message-id from a non-JMS client would round-trip correctly as a correlation-id value. For this reason, and also to accomodate the 4 different types of message-id that the core spec defines (string, ulong, uuid, and binary) and ensure preservation of the AMQP wire type when round-tripping these values into the JMS application layer and back to the AMQP layer, the client manages/translates the message-id and correlation-id values, and utilises the x-opt-app-correlation-id message annotation to record when an application-specific JMSCorrelationID value is in use.
> An issue arises if an application-specific string is sent as the JMSCorrelationID value on a request message (from JMS app A), and received by a a non-JMS app B which then sends a new reply message containing the same correlation-id value. If the non-JMS client/app B does not set the x-opt-app-correlation-id on its reply message, then the JMS app A receiving the reply message will then treat the correlation-id value as being representative of a JMSMessageID value and return incorrectly return an "ID:" prefixed value for the message JMSCorrelationID. This would then no longer match the JMSCorrelationID sent on the original request message.
