No it does work.
You simply decide in your IDE if you are using 1.1 or 1.2.

If you want to use 1.2, then ensure you are compiling against 1.2 base
classes without collections.jar and the import * will catch the Dummy class
I posted. So there are no clashing classes, and the java.util versions will
be used.

If you want to use 1.1 then compile against collections.jar plus the 1.1
classes.zip, and the Dummy class I posted will be ignored, and the
com.sun... versions will be used.
