Annotation is not inherited from interface method
annotations, java
Solution
From the javadocs of `java.lang.annotation.Inherited`:
Note that this meta-annotation type has no effect if the annotated type is used to annotate anything other than a class. Note also that this meta-annotation only causes annotations to be inherited from superclasses; annotations on implemented interfaces have no effect.
Problem
I have an interface with an annotated method. The annotation is marked with `@Inherited`, so I expect an implementor to inherit it. However, it is not the case: Code: ``` import java.lang.annotation.Inherited; import java.lang.annotation.Retention; import java.lang.annotation.RetentionPolicy; import java.lang.reflect.Method; import java.util.Arrays; public class Example { public static void main(String[] args) throws SecurityException, NoSuchMethodException { TestInterface obj = new TestInterface() { @Override public void m() {} }; printMethodAnnotations(TestInterface.class.getMethod("m")); printMethodAnnotations(obj.getClass().getMethod("m")); } private static void printMethodAnnotations(Method m) { System.out.println(m + ": " + Arrays.toString(m.getAnnotations())); } } interface TestInterface { @TestAnnotation public void m(); } @Retention(RetentionPolicy.RUNTIME) @Inherited @interface TestAnnotation {} ``` The above code prints: public abstract void annotations.TestInterface.m(): [@annotations.TestAnnotation()] public void annotations.Example$1.m(): [] So the question is why does not the `obj.m()` have `@TestAnnotation` despite that it implements a method marked with `@TestAnnotation` which is `@Inherited`?
