Damn, I thought I knew every corner of the Java language. Why on earth
should an outer class be able to access private members of an inner
class?

<compilerTrivia mode="extremelyUseless">
The (now dead) Microsoft J++ compiler just changed private fields and
methods to package accessible instead of creating these (lame) accessor
methods (and it also added an attribute to record the real
accessibility). I used to think this was pretty clever, but I just
realized that for instance methods it isn't such a great idea, because
package methods are virtual while private methods aren't. So you can end
up accidentally overriding a private method.
