Client-side mutual TLS, SSLContext created with ssl-config does not seem to be sending client certificate during handshake

[michaelzg]

This is a follow-up to akka/akka-http#1433 where it was observed that setting up a HttpsConnectionContext with a SSLContext created by the Typesafe ssl-config did not work as expected--through debugging there was evidence that during the handshake process the client did not send its client certificate. However, creating the SSLContext manually with java.security allowed the mutual TLS connection to work as expected.

I hope to get some time during a weekend to help get a reproducible example..

I see this issue is somewhat old, is it still valid (or does it need validation refresh), just checking I can use the ssl-config or create everything manually. Thanks!
