quarkus: AsyncHealthCheck does not work with Hibernate Reactive

Describe the bug

The following health check based on the AsyncHealthCheck example from the smallrye-health doc works perfectly fine with Quarkus 1.13.7 when Hibernate Reactive is used:

@ApplicationScoped
@Liveness
public class MyHealthCheck implements AsyncHealthCheck {

    @Inject
    Mutiny.Session session;

    @Override
    public Uni<HealthCheckResponse> call() {
        return session.createNativeQuery("SELECT 1")
                .getSingleResult()
                .replaceWith(TRUE)
                .onFailure().recoverWithItem(FALSE)
                .onItem().transform(dbState ->
                        HealthCheckResponse.named("Health check").status(dbState).build()
                );
    }
}

With Quarkus 2.2.2.Final, the same code no longer works because the call method isn’t run on the Vert.x event loop thread.

Expected behavior

The check should be run on the Vert.x event loop thread.

Actual behavior

2021-09-15 11:09:45,142 ERROR [io.sma.health] (executor-thread-0) SRHCK01000: Error processing Health Checks: java.lang.IllegalStateException: HR000068: This method should exclusively be invoked from a Vert.x EventLoop thread; currently running on thread 'executor-thread-0'
