[SNMP4J] SNMP4j for V3 Traps

[Yukti yatish]

Hi,
     I am using SNMP4j stack in my project.To receive V3 traps I am updating
the V3 credentials using addUser(user,authengineid, usmUser).

I wanted to know, what would the funtionality be incase I add another user
with same username and credentials but null engine id is added in the USM
table

snmp.getUSM().addUser(user1, engineid,usmUser1);
snmp.getUSM().addUser(user1, null,usmUser1);

After the second update, will I start receiving traps from all the NEs with
the same user credentials but different Engine IDs including the first one.
