Much of our CNI code implicitly relies on NullPointerException-on-null 
because its been written for targets which trap memory access exceptions 
and convert them to NullPointerExceptions. Andrew's patch is needed on 
targets that don't have MMUs in order that the behaviour of this code be 
consistent on those targets. Since its a special option that needs to be 
turned on only for specific targets, I would say its better off as a 
compiler option.
