This is a limitation of JAX-RS, you can't inject stuff via CDI into a JAX-RS Application class

[bogedal]

@geoand That sounds odd. I have several Helidon based services running with injected stuff in the JAX-RS application class.

[geoand]

Sure, I'm not saying it can't be done technically.

What I am saying is that because reads this class at build time, injection does not work

[bogedal]

@geoand Do you mean that Quarkus reads this class at build time?

@geoand Do you mean that Quarkus reads this class at build time?

Yes, for RESTEasy Reactive at least.

For RESTEasy Classic, I am not sure, but in any case it's likely read too early for CDI to work

[bogedal]

Ok - Thanks a lot for the very quick responses :)

I have a opened a PR to make this a build time error in RESTEasy Reactive.
