New version of generics compiler (2.2)

A new version of the generics compiler (version 2.2) has been posted at
http://developer.java.sun.com/developer/earlyAccess/adding_generics/.

Compared to 2.0 it seems variant type parameters are gone, wildcard
parameter have been implemented [void addAll(Collection<? extends E>
c);] and 1.4.2 is required. Plus bug fixes and so on.
