Upgrade to Quarkus from 3.15.1 to 3.16.2 (DRAFT)

[rhauch]

DO NOT MERGE. This is a test to see if there are more reliable builds.

There are a few changes to fix memory issues, and with 3.15.1 we are running into a few memory issues. This is the first thing I want to try.

Quarkus 3.15 is the most recent LTS version of Quarkus, so we should update to 3.16 only if that is required to fix the memory issues. And given #156 and #155 both worked on #152, we shouldn't need this upgrade. Closing without merging.
