ActiveMQ to RabbitMQ shovel results in amqp header data being inserted in message data #12455
Description
Describe the bug
As discussed on the Slack thread https://rabbitmq.slack.com/archives/C1EDN83PA/p1727472217316949, when a message is exchanged between an ActiveMQ broker and a RabbitMQ broker using a dynamic shovel some binary data appears at the beginning of the message. This looks like some AMQP control data. The shovel is configured as AMQP 1.0 -> AMQP 1.0, although the issue appears to happen with AMQP 1.0 -> AMQP 0.9.1.
The comment from the team was that the amqp-value data is being copied to the data section, and that the shovel has not been updated for the latest 4.0.2 release.
The issue existed in v3.
RabbitMQ: 4.0.2
amqp-client: 0.1.0
AWS ActiveMQ Version: 5.18.4
Reproduction steps
- Create a dynamic shovel between an Active MQ broker and RabbitMQ, shovel definition below (the same issue occurs with a 1.1 -> 0.9.1 shovel). ActiveMQ is the source broker at 192.168.56.45.
{
"node": "rabbit@host",
"timestamp": "2024-10-05 12:02:22",
"name": "ActiveMQ",
"vhost": "/",
"type": "dynamic",
"state": "running",
"src_uri": "amqp://guest:[email protected]:5672?verify=verify_none",
"src_protocol": "amqp10",
"dest_protocol": "amqp10",
"dest_uri": "amqp://guest:guest@localhost:5672",
"src_address": "OUT_Q",
"dest_address": "IN_Q",
"blocked_status": "running"
}- Exchange a message between the ActiveMQ broker and consume it from the RabbitMQ broker (note the issue can be seen on the RabbitMQ management console where the message will be represented in Base64).
- The consumed message will have a few bytes of binary data appended to it. The message sent is "Message", what is received is "�Sw�Message" (base 64 AFN3oQdNZXNzYWdl).
Expected behavior
The message published by ActiveMQ should be consumed by the client without the binary data.
