The current approach is to print the SSLServerSocket details when a handshake fails due to a ciphersuite/keyexchange config issue

I'm not sure if it is really helpful for developers to understand and debug the failure by reading the additionally dumped cipher suites and/or key exchange configuration.  Given the server cipher suites TLS_AES_128_GCM_SHA256, can one really know the failure reason exactly?

The cipher suite enabled on the server side is not logged when "no common in cipher suites" error is thrown. Hope the developer could find the difference in the cipher suites between client and server.
