So, resumption is supposed to work out of the box if SSLEngine is
created with the (host, port) pair, which we do.
One possible problem can be due to the fact that the "host" is
specified as IP address, while the full qualified name is needed, or
Usually, the server cannot reverse lookup the client, so on server
side it's almost always an IP address.

If you can debug, please verify what is being passed to SSLEngine in
SslContextFactory.newSSLEngine() ?

Also, a comparison between SslContextFactory for 7 and 9 tells something ?
