rev 7982 : 8017513: Support for closeable streams
8022237: j.u.s.BaseStream.onClose() has an issue in implementation or requires spec clarification
8022572: Same exception instances thrown from j.u.stream.Stream.onClose() handlers are not listed as suppressed
Summary: BaseStream implements AutoCloseable; Remove CloseableStream and DelegatingStream
