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

Inverting the annotation to record when values represent a JMSMessageID value (rather than an application-specific string) would simply cause a similar issue whenever a JMSMessageID was set as the JMSCorrelationID value on a request message, and a reply sent by a non-JMS application that didnt understand the annotation and know to send it on any replies.

Thus far, the only route of improvement I have thought of is to begin actually sending the "ID:" prefix on the wire for both JMSMessageID (when the related AMQP message-id value is a string, as we recommend JMS producers use) and JMSCorrelationID. That way the value inherently conveys whether it is a JMSMessageID or application-specific value when it is used as a JMSCorrelationID value, and yet still aligns both message-id and correlation-id uses as having the same AMQP wire value. Any incomming string message-id values roundtripped through JMS and back to the correlation-id field may still need managed if they didnt originally include the "ID:" prefix on the wire. (E.g those from current JMS client impls, and could replies to replies still exhibit issues?).

The main issue with this would be the non-string AMQP message-id/correlation-id values. Those would still lack a way on the wire to convey whether the non-string AMQP correlation-id value originally represented a JMSMessageID value or an application-specific value. The only way to convey that would seem to be using an annotation as currently, in which similar situations could still arise as in the original problem statement.

> 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.
