Annotation not found on parameter in overridden method unless method is public

[sbrannen]

Overview

While writing tests for #35342, I noticed that we have a discrepancy in our "method override" detection in MergedAnnotations and AnnotatedMethod.

Specifically, the MergedAnnotations infrastructure supports finding annotations on methods that override non-public methods (such as a protected or package-private method in a superclass).

However, AnnotatedMethod will not find an annotation on a parameter in an overridden method unless the overridden method is public.

Example

If we remove the public modifier from the following declaration, the shouldFindAnnotationOnMethodParameterInGenericAbstractSuperclass() test in AnnotatedMethodTests will fail.

Line 106 in 5d325ca

public abstract void processTwo(@Param C value);
