Some time ago I sent a path to the ArrayIterator class in the 
collections package.

I just realize that there is still a bug on it.

the method next() should throw a NoSuchElementException
when there is no more elements to return.

So I write another patch and updated the testIterator() metod
in the TestArrayIterator class.

I'm sending the files attached.
