Consider the following little example:
package prv.rli.codetest;
import java.lang.reflect.Method;
public class BreakingInterfaces {
interface Base {
Pardon the furstration, but it must be in a parallel universe where the Javadoc wording adequately explains this behavior: https://docs.oracle.com/javase/8/docs/api/java/lang/Class.html#getDeclaredMethods--. An array of "all the declared methods" turns out to be an array of "all declared methods by the user and by some under-the-hood implementation detail explained on StackOverflow". Even worse, I'm seeing something weird about annotations: I'm overriding a generic method while applying an annotation, and both abstract&default methods returned by getDeclaredMethods() have the annotation, but only the abstract one has the correct non-generic parameters. So it seems to me this implementation detail partly defeats the purpose of searching for a method by annotation.
