I am getting different output for the same code while using java 1.7.0_79 and 1.7.0_80 versions for compilation and running. The test code snippet looks like this :
interface Constraint<T> extends Serializable {
T getValue();
}
@Target({ ElementType.METHOD })
@Retention(RetentionPolicy.RUNTIME)
@interface NonZero {
}
public class ReflectionTest {
@SuppressWarnings("serial")
public static void main(String[] args) {
Constraint<Integer> c = new Constraint<Integer>() {
@Override
@NonZero
public Integer getValue() {
return null;
}
};
for(Method m : c.getClass().getDeclaredMethods()) {
System.out.println("Method :: " + m.toGenericString());
if(m.getAnnotations().length == 0){
System.out.println("No annotations detected");
} else {
for(Annotation o: m.getAnnotations()) {
System.out.println("Annotation :: " + o);
}
}
}
}
}
The output for java 1.7.0_79 is :
Method :: public java.lang.Integer ReflectionTest$1.getValue()
Annotation :: @NonZero()
Method :: public java.lang.Object
ReflectionTest$1.getValue() No annotations detected
And the output for 1.7.0_80 is :
Method :: public java.lang.Integer ReflectionTest$1.getValue()
Annotation :: @NonZero()
Method :: public java.lang.Object ReflectionTest$1.getValue()
Annotation :: @NonZero()
In the code compiled with jdk-1.7.0_80 version, annotation is applied to the parent method while this was not the case in the earlier versions. Why is this difference?
