                 Summary: LinkedHashMap throws NullPointerException when

    _______________________________________________________

Details:

When access order is used, a NullPointerException is thrown because root
becomes null when size() > 0.  This is caused by the access() code violating
the invariant that root.pred points to the newest object.  The attached
one-line patch fixes this instance of the problem, at least.
