Application startup fails using Lombok's @NonNull on a method annotated with @ConsumeEvent

[benjaminrau]

Describe the bug

When annotating a method parameter with @nonnull for a Vertx Consumer Method (means its annotated with @ConsumeEvent) then the application startup fails, throwing an exception.

Mentioned on: #29322

Expected behavior

No exception is thrown when using @nonnull.

Actual behavior

Exception is thrown when using @nonnull, application can not be started.

How to Reproduce?

1. Clone the repo: https://github.com/benjaminrau/quarkus-nonnull-reproducer
2. Start the application

Additional information

Noticable is that @nonnull is included in the ClassName for EventBusCodec registration too:

I'm under the impression that this has the same root cause as #29425. /cc @Ladicek

[Ladicek]

Yeah, that looks very much like the same issue.

[Ladicek]

Okay, it is not the same issue. Looks like someone uses Type.toString() to generate a class name, which is wrong. Let me check.

[Ladicek]

Found it: https://github.com/quarkusio/quarkus/blob/2.14.1.Final/extensions/vertx/deployment/src/main/java/io/quarkus/vertx/deployment/EventBusCodecProcessor.java#L91

Here, entry.getKey() is a Jandex Type, so entry.getKey().toString() may include type annotations. Fix is simple: entry.getKey().name().toString().

Thanks a lot for your efforts! Quarkus is really awesome!
