I tried: @Test public void foo() { bar(null); } void bar(@NonNull String param) { System.out.println(param); } All versions of that annotation let the null right through. I tried with: import lombok.NonNull; import javax.validation.constraints.NotNull; import io.micronaut.core.annotation.NonNull; import org.springframework.lang.NonNull; import reactor.util.annotation.NonNull;
