 Review comment:
   since we are touching this function now, I'd like to also raise one 
discussing about the semantic here. Currently it is totally the application's 
responsibility on managing the semantic on using this API. it would be good to 
add some constraints on this API:
   
   - if entryId is negative  (the fix @eolivelli tried to fix)
   - if entryId is smaller than LAC, that means this entry is a duplicated entry
   
   in both cases, we should fail the addEntry with exceptions.
