is it possible in openjdk 9 to advertise application protocol in the tls handshake?

[Jon Berg]

Hi,

Given that you are acting as a server, it would be nice to be able to offer
"http/1.1" as application.

The purpose of this is to get chrome to do tls false start which require
that the server "advertise" http/1.1 in ALPN or NPN. In the tls handshake.
To do this it is just and integer and that string that has to be included
in the handshake message at the right place...

>From looking at the api it seems that this is not supported.
And from reading http://openjdk.java.net/jeps/244 it sounds as it does
not advertise anything, but for a server socket it is an intersection of
what
the client sends and what the server is capable of.

Can you confirm that this is not supported in openjdk 9?

Thanks,
Jon Berg.
