On a completely clean installation of OH2 Snapshot (#771), you will get the following error when you try to start the new Z-Wave binding:
openhab> bundle:start org.openhab.binding.zwave
Error executing command: Error executing command on bundles:
Error starting bundle 208: Could not resolve module: org.openhab.binding.zwave [208]
Unresolved requirement: Import-Package: gnu.io
To fix this: feature:install openhab-transport-serial and then Z-Wave will start
