New Revision: 1691150
URL: http://svn.apache.org/r1691150
Log:
Add plumbing for ALPN with JSSE (trying to test with HTTP/2 and OpenSSL, but it
crashes during handshake at the moment if protocols have been configured).
Todo: After handshake, the protocol will be read using a new interface that the
SSLEngine will have.
