1.) The new version seems to fix that issue 'No consumers available on
endpoint' but still result in a npe. Injection works fine with @Inject on
@Produce. According to the docs, it should work without inject too.
```
@Dependent
public class CamelRunner {
@Produce("direct:runner")
ProducerTemplate producer;
```
```

2.) Unused bean is removed during build. Adding @Unremovable will not call
onBar anymore.
```
@ApplicationScoped
public class Bar {
@Consume("direct:bar")
public void onBar(String str) {
}
}
```
```
================================================================================
CDI: programmatic lookup problem detected
-----------------------------------------
At least one bean matched the required type and qualifiers but was marked as
unused and removed during build
Removed beans:
- CLASS bean x.y.Bar [types=[class x.y.Bar],
qualifiers=[@javax.enterprise.inject.Default(), @javax.enterprise.inject.Any()]]
Required type: class x.y.Bar
Required qualifiers: []
Solutions:
- Application developers can eliminate false positives via the
@Unremovable annotation
- Extensions can eliminate false positives via build items, e.g. using
the UnremovableBeanBuildItem
- See also https://quarkus.io/guides/cdi-reference#remove_unused_beans
================================================================================
```
```
@ApplicationScoped
@Unremovable
public class Bar {
@Consume("direct:bar")
public void onBar(String str) {
}
}
@ApplicationScoped
public class MutinyTest {
@Inject
CamelContext context;
Subscriber<String> subscriber;
@PostConstruct
public void init() {
subscriber = CamelReactiveStreams.get(context)
.subscriber("direct:foo-notification", String.class);
}
@Incoming("foo-notification") // mutiny
public void consume(String notify) {
subscriber.onNext(notify);
}
}
from("direct:foo-notification").to("direct:bar");
