libspin-java binary package in Ubuntu Xenial amd64

 Swing is the standard component architecture for developing Java desktop
 applications. Its exhaustive collection of widgets is the foundation for
 easy development of rich graphical user interfaces (GUI).
 .
 Alas every non trivial GUI sooner or later encounters the problem of
 "freeze". This annoying behaviour is experienced by users every time the
 application performs extensive calculations or blocks for network or disk
 I/O.
 .
 Spin offers a revolutionary new approach. It offers transparent thread
 handling with minimal impact on your application code.
