Iterable<? extends JAVAFileObject>

You'd think a JAVAFileObject[] or a JAVAFileObject...'d fullfil
that requirement, but it does not. It fills it sufficiently to do a
for:each but not to satisfy this parameter.

That is like a piece of purple lint

A {Unix} {C} language processor which carries out more
	thorough checks on the code than is usual with C {compilers}.

	Lint is named after the bits of fluff it supposedly picks from
	programs.  Judging by references on {Usenet} this term has
	become a shorthand for {desk check} at some non-Unix shops,
	even in languages other than {C}.  Also used as {delint}.

People say arrays and generics do not mix, but they damn well SHOULD.

A language proposed by Cii {Honeywell-Bull} to meet the DoD
	{Ironman} requirements which led to {Ada}.  This language won
	in 1979.

A workaround, of course, is passing in

Arrays.asList(p)

where p is JAVAFileObject[].

I agree that it's a blemish, though.

Posted via a free Usenet

<messaging> /yoos'net/ or /yooz'net/ (Or "Usenet news", from
	"Users' Network") A distributed {bulletin board} system and
	the people who post and read articles thereon.  Originally
	implemented in 1979 - 1980 by Steve Bellovin, Jim Ellis, Tom
	Truscott, and Steve Daniel at Duke University, and supported
	mainly by {Unix} machines, it swiftly grew to become
	international in scope and, before the advent of the
	{World-Wide Web}, probably the largest decentralised
	information utility in existence.

	Usenet encompasses government agencies, universities, high
	schools, businesses of all sizes, and home computers of all
	descriptions.  In the beginning, not all Usenet hosts were on
	the Internet.  As of early 1993, it hosted over 1200
	{newsgroups} ("groups" for short) and an average of 40
	megabytes (the equivalent of several thousand paper pages) of
	new technical articles, news, discussion, chatter, and
	{flamage} every day.  By November 1999, the number of groups
	had grown to over 37,000.

	To join in you originally needed a {news reader} program but
	there are now several web gateways such as {Deja
	(http://www.deja.com/)}.  Several {web browsers} include news
	readers and {URLs} beginning "news:" refer to Usenet
	newsgroups.

	{Network News Transfer Protocol} is a {protocol} used to
	transfer news articles between a news {server} and a {news
	reader}.  The {uucp} {protocol} was sometimes used to transfer
	articles between servers, though this is probably rare now
	that most sites are on the {Internet}.

	{Stanford University} runs a service to send news articles by
	{electronic mail}.  Send electronic mail to
	<netnews@db.stanford.edu> with "help" in the message body.
