quarkus: Devmode reload broken, NPE in `io.q.deployment.dev.ClassComparisonUtil` - "Cannot invoke "org.jboss.jandex.ClassInfo.flags()" because "old" is null"

Describe the bug

Suddenly, the below has started happening. This is only in the last few days, and I’m not sure if I can recall any change which prompted it:

What is interesting is that this only seems to happen when launched via ./gradlew quarkusDev If I launch Quarkus by clicking “Start” in IntelliJ through the IDE launcher, it doesn’t happen

Unfortunately, attaching a reproducer may be hard because the codebase isn’t open-source and I’m not sure how to minimize it while removing all confidential code and keeping the same behavior 🙁
