ok, now I got the error.... It is not sufficient to give the engineId to 
the USM, it must be set on the MPv3 object, too:

It will work, if you change the createSnmpSession function to:

if (version == SnmpConstants.version3) {
   byte[] tt = {01,02,03,04,05,06};
   MPv3 mpv3 =
       (MPv3)snmp.getMessageProcessingModel(MessageProcessingModel.MPv3);
   mpv3.setLocalEngineID(tt);

   USM usm = new USM(SecurityProtocols.getInstance(),
                     new OctetString(mpv3.getLocalEngineID()), 0);
   SecurityModels.getInstance().addSecurityModel(usm);
   addUsmUser(snmp);
}
