Marc Veary commented on PLUTO-391:
----------------------------------

Actually, it won't be an issue for an implementation (no default) of the 
PortletPreferencesService - end-of-the-week ;-)

> DefaultPortletPreferenceService#clonePreferences can return a null instead of 
> an empty array and cause a NullPointerException

> The DefaultPortletPreferenceService class has a private method 
> clonePreferences() that can return 'null' whereas it should instead return an 
> empty array.  The value returned is used in a for-loop in another methd 
> without any check for the array object being null.
