      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

      $ javac -fullversion -XDrawDiagnostics -Xlint:processing -processor P A.java
      javac full version "1.8.0_162-ea-b03"
      ... no warnings

      # JDK 9
