Fix sonars from dependency upgrade

The dependency upgrades in policy-parent caused some new sonars.  In
particular, initMocks() has been deprecated - replaced with calls to the
Mockito Runner.  Changed one to openMocks() because using the Runner
caused it to fail on jenkins, but not in the local eclipse.
Also fixed a type safety issue with EMPTY_LIST.
