WS call does not work in play-1.3.0RC2-12-g87e2d3c

Reported by Chris Webb | November 18th, 2014 @ 11:30 AM | in 1.3 (closed)

I have the following WS call in my application which works on play-1.3.0RC1-58-gf7d6d6 but does not on play-1.3.0RC2-12-g87e2d3c both on top of Oracle JDK 1.8.0_05-b13

MailChimpSubscribe subscribe = new MailChimpSubscribe(...);
WS.url("https://" + datacenterPrefix + ".api.mailchimp.com/2.0/lists/subscribe.json")
    .body(new Gson().toJson(subscribe))
    .setHeader("Accept", "application/json")
    .onRedeem(new Action<F.Promise<HttpResponse>>() {
        public void invoke(Promise<HttpResponse> result) {

When I turn on the logging for the AsyncHttpClient I noticed that chunking has been enabled on play-1.3.0RC1-58-gf7d6d6, see below:

play-1.3.0RC1-58-gf7d6d6 request (using AsyncHttpClient v1.8.9):

Request DefaultHttpRequest(chunked: false)
POST /2.0/lists/subscribe.json HTTP/1.1
Host: us5.api.mailchimp.com
Accept: application/json
Content-Type: application/json
Connection: keep-alive
User-Agent: NING/1.0
Content-Length: 174

play-1.3.0RC2-12-g87e2d3c request (using AsyncHttpClient v1.8.13):

Request DefaultHttpRequest(chunked: true)
POST /2.0/lists/subscribe.json HTTP/1.1
Host: us5.api.mailchimp.com
Accept: application/json
Content-Type: application/json
Connection: keep-alive
User-Agent: NING/1.0
Transfer-Encoding: chunked

I'm not 100% sure that the chunked transfer encoding is causing the problem but that's the only thing that I can see that has changed. There has been no change to WAAsync in that time so I'm assuming it's a change to the underlying AsyncHttpClient, which was updated on 4/9/14 from v1.8.9 to v1.8.13. I rolled back AsyncHttpClient to v1.8.9 and indeed the web service call worked. I then rolled forward until it broke which was v1.8.12. So it looks like v1.8.11 has the same functionality as 1.8.9. I had a quick look at the AsyncHttpClient commits between 1.8.11 (released 17/6) and 1.8.12 (released 1/7) but couldn't see anything that would affect the chunked enabled status.

Has there been an API change in AsyncHttpClient?

<h2>Play framework</h2>

Play makes it easier to build Web applications with Java. It is a clean alternative to bloated Enterprise Java stacks. It focuses on developer productivity and targets RESTful architectures. Learn more on the <a href="http://www.playframework.org">http://www.playframework.org</a> website.<br><br>

<h2>Creating a bug report</h2> Bug reports are incredibly helpful, so take time to report bugs and request features in our ticket tracker. We’re always grateful for patches to Play’s code. Indeed, bug reports with attached patches will get fixed far quickly than those without any.<br><br>

Don't have too much expectations. Unless the bug is really a serious "everything is broken" thing, you're creating a ticket to start a discussion. Having a patch (or a branch on Github we can pull from) is better, but then again we'll only pull high quality branches that make sense to be in the core of Play.
