      Description

      ALPN (Application Layer Protocol Negotiation) [1] is a TLS extension to enable
      clients and servers to negotiate the application-level protocol that will
      be carried over TLS.

      In JDK 9 new APIs were introduced to set and get application protocol names.
      These values are set in advance by TLS clients and servers and then exchanged
      during the TLS handshake. See JEP-244 (http://openjdk.java.net/jeps/244).

      Subsequently, a specific use-case was identified that is not addressed
      by our APIs. HTTP servers that support HTTP/2 [2] are constrained in their
      choice of cipher suite and are therefore unable to select the application
      protocol name in advance. Instead they must defer selection until after
      the TLS cipher suite is known.

      We need to introduce an API to enable such servers to set the application
      protocol name during the TLS handshake.
