Jclouds httpresponse API does not include content-length when downloading an artifact

[Dhivyaa21]

I am trying to get the content-length header while downloading an artifact from artifactory. I could see all the headers returned in the response object but content-length and content-type. Download artifact request returns all the headers when I use other clients (Postman, java httpclient, chrome browser etc).
Gradle debug log prints all the headers returned by the API but it is not the same in the response headers returned by the httpresponse object
I am not sure if jclouds has a restriction on the number of headers returned via the httpresponse object.

Expected Behavior

jclouds httpresponse object returns all the response headers

Steps to Reproduce (for bugs)

I created a pojo called DownloadContent

@AutoValue
public abstract class DownloadContent {
    @Nullable
    public abstract InputStream inputStream();

    @Nullable
    public abstract Integer contentLength();

    @SerializedNames({"inputStream", "contentLength"})
    public static DownloadContent create(InputStream inputStream, int contentLength) {
        return new AutoValue_DownloadContent(inputStream, contentLength);
    }
}

parser to parse the jclouds httpresponse object returned by the ArtifactAPI

public class InputStreamContentParser implements Function<HttpResponse, DownloadContent> {

    @Override
    public DownloadContent apply(HttpResponse response) {
        int contentLength = 0;
        Map<String, Collection<String>> headers = response.getHeaders().asMap();
        if (response.getHeaders() != null && response.getHeaders().containsKey("content-length")) {
            contentLength = Integer.parseInt(response.getHeaders().get("content-length").toArray()[0].toString());
        }
        try {
            return DownloadContent.create(response.getPayload().openStream(), contentLength);
        } catch (IOException e) {
            throw new RuntimeException(e.getMessage());
        }
    }
}

Then I add this parser to the download API

@Named("artifact:download")
    @Path("/{repoKey}/{itemPath}")
    @Fallback(Fallbacks.NullOnNotFoundOr404.class)
    @Consumes(MediaType.WILDCARD)
    @ResponseParser(InputStreamContentParser.class)
    @GET
    DownloadContent downloadArtifact(@PathParam("repoKey") String sourceRepo, @PathParam("itemPath") String sourcePath,
                                     @QueryParam("skipUpdateStats") boolean skipUpdateStats);

I ran a live test on my local instance of artifactory. The following are the jclouds log returned by gradle for download request

The headers returned by the jclouds httpresponse object in InputStreamContentParser are as follows

Keep-Alive:[timeout=75]
    Server:[openresty]
    X-Checksum-Sha1:[60fde9c2310b0d4cad6b04387efba289]

    ETag:[60fde9c2310b0d4cad4dab8d126b04387efba289]

The number of headers is always 15.

Your Environment

Any help on this issue is much appreciated! Thanks!
