Send an HTTP response with trailers using the Java HTTP Server

Using the default implementation of the HTTP server shipped with the JDK (the com.sun.net.httpserver package), how do I send any trailers after I've written out the HTTP response body?

HTTP/1.1 200 OK
Content-Type: text/plain
Transfer-Encoding: chunked
Trailer: Expires

7\r\n
Mozilla\r\n
9\r\n
Developer\r\n
7\r\n
Network\r\n
0\r\n
Expires: Wed, 21 Oct 2015 07:28:00 GMT\r\n
\r\n

It's quite possible to enable the chunked Transfer-Encoding by calling HttpExchange.sendResponseHeaders() with a zero responseLength.

Yet, I'm looking at the source code of sun.net.httpserver.ChunkedOutputStream as well as its usages, but it seems that support for trailers is not implemented.
