As stated in the release notes (http://blog.fuseyism.com/index.php/2012/06/13/security-icedtea-2-1-1-2-2-1-released/)
the 2.2 series is known not to work with Zero.  It's my understanding that there
is more to this than just removing a few method calls, but I'll leave Andrew Haley
and Chris Phillips to comment on this, as they know the details in this area.

For Zero, you should use 2.1.1.
