<p class="MsoNormal"><span lang="EN-US">I’ve debugged a lot today and tried to get something out of the javax.net.debug output but I didn’t get any further with this – probably due to my lack of understanding the details of TLS communication and its implementation.
I know the server is using some legacy protocol but still I think it should work.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">Maybe someone has any helpful idea? Is it a bug? You can simply try to run my test code snippet and should see the issue immediately…<o:p></o:p></span></p>
