Hopefully some day we would have fixed:
Bug 6373386 <http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6373386> - Method chaining for
instance methods that return void
That would prevent us from such bloated sub classes.
Hopefully such "workarounds" would not force later incompatibilities

But why are you overriding this in the first place ??? There seems to be
no change in functionality or specification.
I missed the covariant change to the return type from AbstractStringBuilder to
StringBuilder.
I also suggested in email that the above could simply be:
return super.append(n, cs);
but that would also need a cast to StringBuilder. So what Jim has is fine.
