parent class methods not accessible in some cases

What steps will reproduce the problem?
1. Create a package-private parent class P with final field X, field 
constructor P(X x) and a public getter X getX().
2. Create a public child class C extends P.
3. call having(on(C.class).getX(), anyStringMatcher).

What is the expected output?

Lambda#having will return a matcher.

What do you see instead?

What version of the product are you using? On what operating system?

2.3.3
windows

Please provide any additional information below.

There are several solutions any of which circumvents the problem:
1) Override public getter in child class (inside call parent's getter, of 
course)
2) Create a no-arg constructor in child class (call super constructor with 
anything, can be nulls and zeros)
3) Declare parent class public

In my case, number 2 is the least-painful provided I add a comment explaining 
the cryptic no-arg constructor, but all of the above is dirty hacking because 
my classes have to be adjusted for outside usage using LambdaJ of which they 
know nothing.

Can this be avoided somehow?
