Thank you Justin. I upgraded to 11 on my dev box, then installed 2.22 and it now displays my messages -- although I don't see when I can view the message content, which is something I could do on the Classic console. I can live with that.
I'm not entirely sure we can upgrade to 11 on our prod box (running on a gov't air-gapped secure network), but I will look into it. The nice thing is I can install it alongside 8 -- assuming I can install it at all -- and use the alternatives system to switch it out. Anyway, thanks for your help again. I think I can muddle through this.

Both ActiveMQ "Classic" and Artemis have moved on from Java 8 for the latest releases. "Classic" made the transition in 5.17.0 and Artemis in 2.20.0. That said, there are still branches where Java 8 releases are possible, but those releases would be for bug fixes only and would not have any new features. The 2.19.1 release was like that. It's technically possible to do another 2.19.x release, but there's currently nothing scheduled. You always have the option of cherry-picking fixes and building your own release. Any seasoned Java developer could manage that. In any event, I would strongly recommend moving beyond Java 8 at this point. From what I can tell much of the Java world has already done so. > ...we work on a secure network that is not always up to the latest and greatest... For what it's worth, Java 11 is not the "latest and greatest." That distinction goes to Java 18 at this point. Java 11 was released almost 4 years ago in September 2018 and Java 17 (the latest LTS release) came in September 2021. But I digress.
