How do I provide create a CloseableHttpPipeliningClient that doesn’t validate SSL certificates?

I’m trying to use Apache HttpAsyncClient with HTTP pipelining support. I want to add a trust-all SSL strategy similar to what’s discussed here Ignoring SSL certificate in Apache HttpClient 4.3 (and a bunch of other places). But I don’t see any way to get a pipelining client builder using the custom SSLContext: the HttpAsyncClients.createPipelining() method doesn’t return a builder, and HttpAsyncClients.custom() builder doesn’t build a ClosableHttpPipeliningClient
