Play WS Native Transport

Play Framework
1

Is it possible to use native transport with Play WS? I’ve searched through GitHub - playframework/play-ws: Standalone Play WS, an async HTTP client with fluent API, but I can’t find anything about it. I know it should be an option on AsyncHttpClient, but I can’t figure out if it is supposed to be possible to use with Play WS.

Yes, because you can pass an already created instance of AsyncHttpClient to PlayWS. See the StandaloneAhcWSClient constructor.

Do you know how to deal with the shaded versions of AsyncHttpClient? If I try to construct an instance of AsyncHttpCient with setUseNativeTransport(true), I get errors trying to find the shaded native transport file. I’m not very familiar with shading though.
