So the handshake is still timing out, but the exception isn't being reported.
I'm also not seeing the "route fully established" messages associated with
successful TCP/IP connection establishment.
> TLS handshake timeouts cannot be controlled through RequestConfig
> -----------------------------------------------------------------
>
> Key: HTTPCLIENT-2135
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2135
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpClient (classic)
> Affects Versions: 5.0.3
> Reporter: Ryan Schmitt
> Priority: Major
> Fix For: 5.2-alpha1
>
>
> Apparently as a consequence of HTTPCLIENT-2091 and/or HTTPCLIENT-2099, TLS
> handshake timeouts can no longer be specified through any of the three
> {{RequestConfig}} timeout parameters (connect, connection request, response).
> The only way to limit TLS handshake duration is through low-level socket
> configuration (socket timeout), which of course affects more than just TLS
> handshakes.
