These methods probably should be public.

[dmlloyd]

Any time you have a constructor or method which is private but called from a nested or enclosing class, the compiler has to produce a "fake" member with package-private access which calls the private member. Sometimes this process goes awry. Therefore it's usually better to make such members be package-private in the first place instead of private.

Changes suggested by @dmlloyd incorporated.
