I tried hard with the s_client but it can limit the protocols to one or another but it canot mix-and-match (hello 1.2, ok we will do 1.0) like Java 8 does. Either TLSv1 or TLSv1.2 but not both. Neither can curl which is also on top of openssl. Today, I spent 2.5 hours with a lemming from MS getting basically nowhere. I really need an engineer, but they give me those clueless support people that is wasting mine and their time. If someone knows how to escalate or a forum where MS developers hang out, I would appreciate it. The support person I got today was clueless, went over a script and any attempt to explain a little more technical details led to total confusion and rebooting the script to beginning. Totally frustrating. At least with Oracle I got to talk with an actual engineer...

This absolutely makes sense, though, since SSL should just die. :) > I've opened support case both MS and already there is a bug filed with > Oracle on this and really, to be absolutely certain if the issue is in > Java or SChannel, one would have to write a non-Java client that that > mimics the handshake messages send from Java with something like > OpenSSL or NSS or whatever and see if the bug replicates.
