Hello,

We are observing an issue with JClouds while transferring a file with an input stream only.
We are opening an input stream to a remote file and we are passing the stream to the JClouds library, but after some time it fails with the following error:

{noformat}

Note: The issue occurs only for larger files (more than 32 mb).

If we pass a BufferedInputStream the code works, so I guess that there is some issue with the processing of the stream. The stream returned by the Java Http Client is HttpResponseInputStream.

Code:

                var userInfo = uri.getUserInfo();
                if (userInfo != null) {
                    var separatorIndex = userInfo.indexOf(':');
                    var username = userInfo.substring(0, separatorIndex);
                    var password = userInfo.substring(separatorIndex + 1);
                    return new PasswordAuthentication(username, password.toCharArray());
                }
                return super.getPasswordAuthentication();
            }
        };
    }

    private static HttpResponse<InputStream> callRemoteEndpointWithRetry(HttpClient client, String decodedUrl) throws Exception {
        var response = client.send(buildFetchFileRequest(decodedUrl), HttpResponse.BodyHandlers.ofInputStream());
        if (response.statusCode() / 100 != 2) {

    }

    private static HttpRequest buildFetchFileRequest(String decodedUrl) {
        var builder = HttpRequest.newBuilder()
                .GET()
                .expectContinue(true)
                .headers("Content-Type", "multipart/form-data")
                .timeout(Duration.ofMinutes(30));
        var uri = URI.create(decodedUrl);
        var userInfo = uri.getUserInfo();
        if (userInfo != null) {
            builder.uri(URI.create(decodedUrl.replace(userInfo + "@", "")));
        } else {
            builder.uri(uri);
        }
        return builder.build();
    }

}
{code}

Could you please take a look? Any advice would be helpful. The one thing I see differences between the HttpResponseInputStream and the BufferedInputStream is that HttpResponseInputStream::isAvailable returns 0. But I'm not sure if that's the issue because the skip of the stream is done by just reading it.

Note: Removed the binary content from jclouds-wire.log

Thanks!
