Incorrect Play 2.5.x JavaWS documentation page

The following section of the documentation states that the WS client does not support streaming upload:

https://www.playframework.com/documentation/2.5.x/JavaWS#Accessing-AsyncHttpClient

It's not very clear from just the link to FeedableBodyGenerator how exactly we are supposed to solve this problem, but more importantly the WS client does in fact support streaming uploads! Depending on which method signatures you are looking at it may not look like it, and checking the documentation will confirm that incorrect assumption. Suppose you have a bytestring source and you want to POST it somewhere.

ws
  .url("http://foo")
  .post(/* many things are allowed here, but nothing that helps */);

The overloads for the post and similar methods on WSRequest don't support streaming, however it is supported just fine with setBody:

ws
  .url("http://foo")
  .setBody(mySource)
  .execute("POST");

Where mySource is an instance of akka.stream.javadsl.Source<ByteString, ?>.

Start with the JavaWS documentation section at https://www.playframework.com/documentation/2.5.x/JavaWS#Accessing-AsyncHttpClient and verify the current statement about streaming uploads. Update the section to explain the setBody(mySource).execute("POST") approach and remove the incorrect claim that streaming uploads are unsupported.
