When starting the AS with IPv6 addresses (for example)

./run.sh -c all -b [3ffe:ffff:100:f101::2] -u [ff0e::1:2:3]

we see the following message on the console:
INFO [SnmpAgentService] SNMP agent going active
ERROR [TrapEmitter] SNMP send error for localhost/127.0.0.1:1162: <java.security.InvalidParameterException: Buffer overflow error converting IP address>

When starting the AS using IPv4 addreses, the SnmpManagers use the jboss.bind.address when sending traps, so it appears that the use of localhost is incorrect.
