        Description

        The JDK 9 javac emits annotations.without.processors warnings that were not present with JDK 8, and which appear to be incorrect:

        === P.java
        import java.util.Set;
        import javax.annotation.processing.AbstractProcessor;
        import javax.annotation.processing.RoundEnvironment;
        import javax.annotation.processing.SupportedAnnotationTypes;
        import javax.lang.model.SourceVersion;
        import javax.lang.model.element.TypeElement;

        @SupportedAnnotationTypes("*")
        public class P extends AbstractProcessor {

          @Override
          public SourceVersion getSupportedSourceVersion() {
            return SourceVersion.latestSupported();
          }

          @Override
          public boolean process(Set<? extends TypeElement> annotations, RoundEnvironment roundEnv) {
            return false;
          }
        }
        === A.java
        @Deprecated
        class A {
        }
        ===

        # JDK 8
