        Find the first Method of the supplied class or interface that meets the specified criteria, beginning with the specified class or interface and traversing its enclosing classes until such a method is found or the top level class is reached.

        The algorithm does not search for methods in Object.

        Parameters:
        clazz - the class or interface in which to find the method; never null
        methodName - the name of the method to find; never null or empty
        parameterTypes - the types of parameters accepted by the method, if any; never null
        Returns:
        an Optional containing the method found; never null but potentially empty if no such method could be found

        Parameters:
        context - the context for which to find all (parent) contexts; never null
        Returns:
        a list of all contexts, "outwards" in the getParent-order, beginning with the given context; never null or empty

        Replaces all primitive types with the appropriate wrapper types. Returns the passed argument if it's not a primitive according to Class.isPrimitive().
        Returns:
        the wrapped class of the primitive type, or the passed class
