I have created bridge between TIBCO queue and WL (version 10.3) queue.
And sent message on TIBCO queue with ReplyTo queue value set. Text Message is passed successfully to WL queue but replyTo is null.
All other header values like messageID, correlationID, priority are received correctly.
Check this Doc Id.
