>
> The patch I will attach does a couple things:
> Uses FileLineIterable/Iterator for iterating over lines of a file. This is
> slightly tidier, but also addresses a few subtle issues across the code base,
> where reading of files did not always end by closing the stream, or, relied
> on platform default character encoding.
> Uses IOUtils consistently to close Closeables, swallowing and logging
> exceptions in cases where they are not to be treated as errors.
> Finally, fixes some issues in ARFFIterator while I'm at it -- hasNext()
> changes state, when next() should, and next() did not throw
> NoSuchElementException
