Agreed.  I really didn't want to to open his can of worms, though.  To
me it seems we have two questions that can be addressed separately - do
we want to require Java5 and do we want to break API compatibility.

It is quite possible the answer is yes to both.  OTOH we could do this
in two steps and release the accumulated bugfixes in a 1.2 version that
already requires Java5 but doesn't break any APIs and then redesign for
2.x using genrics and whatnot.

Basically yes,
only that I wouldn't implement it in Java 1.4 at all.
