Expected behavior

If this property cannot be updated at runtime, it would be described in documentation and mentioned to the user in DEV UI.

Actual behavior

No response

How to Reproduce?

1. Start the quarkus dev mode
2. Go to dev ui
3. Go to configuration tab
4. Activate the property quarkus.arc.dev-mode.monitoring-enabled. A notification appears to acknowlegde the update.

The quarkus console indicates that reload is done

INFO [io.qua.dep.dev.RuntimeUpdatesProcessor] (vert.x-worker-thread-1) Live reload total time: 0.173s

5. Try to GET /hello or any other endpoints and you will see the stacktrace mentioned before.

[mkouba]

Yes, this was never supported. A change in quarkus.arc.dev-mode.monitoring-enabled requires a full rebuild, i.e. we need to document this requirement.

[manovotn]

The config property now has a javadoc that explains it needs a rebuild to operate properly.
