Unable to deliver messages through a mixed version broker network

• Key: AMQ-1472
• Type: Bug
• Status: Resolved
• Resolution: Fixed
• Priority: Blocker
• Assignee: Rob Davies
• Reporter: Jason Vasquez
• Affects Version/s: 5.0.0
• Fix Version/s: 5.0.0

Description

Setup:

Client Producer:	5.0-SNAPSHOT
Broker A:	4.1.1
Broker B:	5.0-SNAPSHOT
Client Consumer:	5.0-SNAPSHOT

Messages from the producer are sent to Broker A, which discovers Broker B via standard multicast discovery (each broker was given a unique name before starting). Consumer is connected to Broker B, set to consume messages from the same queue.

After a small number of successful transfers, (I've seen between 0 and 7) Broker B will display this message on each send attempt by the producer, and break the network connection between Broker A and B (which is re-established immediately):

Seemed like this might be relevant – here's the directory structure for Broker B's data directory – note data file named data-kaha-1 vs. data--1:

$ find data                                                                                                                         3:13PM

we only support 4.1.1 clients connecting to 5.0 brokers. The behaviour of networks between mixed brokers is undefined (not supported)
