Incompatibility between Mina and Android Lollipop

[Yuri Samoilenko]

Hello.

I'am not watching for KDE connect carefully(and I dont know how Mina is
used now), but Mina was added by me as simple embedable ssh-server. So if
there is another ssh-server implementation of ssh-server for Java it can be
used as drop-in replacement. There is a very few lines of code to
instantiate ssh-server with Mina so migration must be simple.
