      Since JDK 1.1, I'm a very active user of the reflection API.
      I'm developing an interpreter, and must use the advanced
      features of this API.

      The new flag in "AccessibleObject" is convenient. I can now
      access the field of another package (that I develop) without
      having to declare the field as "public".

      But things are more complicated with overloaded methods.
      When a method is called, my interpreter needs to determine
      the best match depending on the given parameters. My
      problem is:

      "Given a Class object, a method name and an array of Class
      objects (deduced from the parameters), how to find the
      Method object (public or not public) that is maximally
      specific."

      If the concerned method is public, I can use
      Class.getMethods() to retrieve all the public methods and
      then to determine the best match.

      If the concerned method is not public, I would like to issue
      an warning, or then use the flag in "AccessibleObject" to
      turn on the accessibility.

      In this case, I have to use Class.getDeclaredMethods(),
      then to determine the best match, and I have to go through
      the whole class hierarchy to make sure that the best match
      is really the best. This is a difficult coding and many
      developers will make bugs.

      So I would like that JDK provides a method that returns
      the Method object (public or not public) having a given
      name, and that is maximally specific in regard to the
      passed parameters classes. I believe that this feature will
      be very useful.
