Hi, What agent are you using (i.e., SampleAgent)? From the output you quoted, I cannot see 1. that a "secrect" community existed and 2. that it was removed successfully and 3. that it does still work after that.
Have you set the CoexistenceProvider of the BaseAgent to your CommunityMIB instance? Although keep in mind, that the access restrictions are handled by the VACM. The Community MIB only provides mapping (coexistance) information. If the Community MIB implementation is not set as coexistance information provider, the community name is directly used as security name by SNMP4J-Agent.
