The container source repository contains some Arquillian tests at tests/arq. These haven't been worke on since at least 2018. Since 2020, on several occasions we have been notified that a component referenced in the Arq tests is out of date and has security problems. Most recently

https://github.com/jboss-container-images/openjdk/security/dependabot/1

I've delayed removing the Arq tests, hoping that we would have time to re-evaluate their value. But we haven't done that; they cause a (small) amount of work and false positives whilst they are around, and are so stale I don't think they provide any value.

They can easily be restored at a future date.
