If load a property object from a XML stream from a http request then it would fail with IOException: stream is closed.

The cause is that ChunkedInputStream does not accept a read after a close. The problem occur only if there is a cache like with JNLP. With a cache it will detect with a read if there is EOF.

The bug might be in HttpInputStream.close(). It should not call after a first close(). A possible fix can be to set the outputStream to null on a call of close.

        @Override

        public void close () throws IOException {
            try {
                if (outputStream != null) {
                    if (read() != -1) {
                        cacheRequest.abort();
                    } else {
                        outputStream.close();
                    }
                }
                super.close ();
            } catch (IOException ioex) {
                if (cacheRequest != null) {
                    cacheRequest.abort();
                }
                throw ioex;
            } finally {
                HttpURLConnection.this.http = null;
                checkResponseCredentials (true);
            }
        }
 

This problem occur with all Java versions.

A workaround is to copy the stream in another stream.
