If you write could that has one class invoking a private
constructor in another class, and this access should be legal
because one class is declared in the other or they are both
enclosed by another, javac generates a synthetic inner class
to make this work.

For example, when compiling the following code:

public class PrivateConstructor {
        private PrivateConstructor() {}
        static class A {
                PrivateConstructor f() {
                        return new PrivateConstructor();
                        }
                }
        }

javac generates the class PrivateConstructor$1. However, the
generated innerclass attribute for PrivateConstructor$1 is:
      static PrivateConstructor$1( [index = 0], "1")

My understanding of the Java Inner class specification is that
the inner_name_index for this attribute should be 0, both
because PrivateConstructor$1 is a (synthetic) anonymous class
and because "1" is not a valid Java identifier.
