>> One corner case that I meant to ask about is the expected behavior when someone attempts to do something on a CloseableStream after it is closed? It's not specified so it's not testable but I'm just wondering if the Iterator throwing ISE is right or whether this should be an UncheckedIOException. As I understand it, an ISE will be thrown if someone attempts to use a stream that already been operated on, so this really just leaves the uninteresting case where the stream is closed before using it.

Answer myself, as end of stream expected.
