OK, last one, and then maybe we should take this "offline" because it
is not a Java linux question...
A "final" parameter is REQUIRED by the compiler if the variable is
referred to by an inner class.
All local variables must be declared final when referred to by inner
class definitions. This includes paramaters. This is required in
order to maintain the relationship between the outer object and the
inner object.
