Wow.  Thanks for clueing me in.  Reminds of the clarify.html whose
web copy never learned to mention its errors were superceded.

Yes independently while disconnected eventually I saw:

adding_generics-2_4ea/README 
confirms: "src ... As the compiler is written using generics, if you
want to bootstrap, you  
will need to use a generic-extended Java compiler.   Use the " source
1.5" compiler flag  
...".

Real life isn't that simple?  Same as normal?  Specifically this
morning we collected the google key "does not point to a working J2SE
1.4.2 installation" from the episode of pain:

A colleague of mine in real life recently made quite a point of
explaining how automagically this download just plain
works ...  I said we should remember we have involved
by-design-unreasonable computers and the stunningly
ignorant me.

So far I think I'm winning, but I see it could work someday.
