> Fix For: Nightly Builds

> This patch can be applied to the current svn checked out version of cli2
> (2010-Feb-9th).
> It will make the cli2 compatible to JDK 5 generic type, eliminating all
> compiling warnings,
> and fix some minor but critical iterator boundary check bugs.
> The bug could be found in the following way: creating some Option object
> WITHOUT description,
> and use a HelpFormatter to print the helping message, then a
> NoSuchElementException will be thrown.
> This is because the HelpFormatter.printHelp() did not correctly check the
> empty status of descriptionIterator.
> And moreover, some implementation of Option.processParent() method did not
> check the empty status
> of the argument "ListIterator<String> arguments".
