Java's TLS library is not OpenSSL. This is not the right list
for help with TLS in JDK8. Speculatively, the timeout might be
related to IPv6 being enabled on the board with JDK8 and Linux 4.x.
Perhaps you're trying the IPv6 address, timing out, and then failing
over to IPv4. Or some middle-box is choking on larger client hellos.
You'll need to analyze a packet capture.

Curl may well be using OpenSSL, but that's not where you're seeing
a problem, so the help you'll get on this list is rather limited.
Try wireshark or similar.
