Hi there, Active MQ is our default Message Broker for asynchronous communication.
ActiveMQ support has been removed <https://github.com/spring-projects/spring-boot/issues/28591>from Spring Boot 3/Framework 6 due to ActiveMQ client not supporting a JMS 3.0 client. Due to the migration from *javax.jms* to the *jakarta.jms* in JEE9 it looks like it won't be possible to use JMS 1/2, so we won't be able to use Active MQ client as-is. We use Spring Cloud Stream <https://community.backbase.com/documentation/ServiceSDK/latest/use_spring_cloud_stream> to abstract the message broker, so there is an opportunity to swap to a different broker. We could also explore Artemis, the next major version of ActiveMQ (v6) with a JMS 3.0 client. Our doubt is: is the community interested in a JMS 3.0 client for ActiveMQ? we could work on it and create a PR in https://github.com/apache/activemq, any thoughts? We also tried a byte code transformation of ActiveMQ client to change imports from javax.jms to jakarta.jms using the *maven-shade-plugin*. but it feels a little bit hacky to put that in Production. Thanks in advance
