Error description

  • Error Message: When an IBM i system is configured to use IPv6,
    the InetAddress.getLocalHost().getHostName() call never returns
    the Fully Qualified Domain Name (FQDN).
    Conversely, when an IBM i system is configured to use IPv4, the
    FQDN is correctly returned.
    .
    Stack Trace: N/A
    .
    

Local fix

  • Use an IPv4 configuration on IBM i.
    

Problem summary

  • The problem is caused by the Inet6AddressImpl.getLocalHostName()
    API. When run on IBM i, the native method uses the wrong logic
    to retrieve the FQDN.
    

Problem conclusion

  • This defect will be fixed in:
    5.0.0 SR12
    .
    The Inet6AddressImpl.getLocalHostName() API has been updated for
    IBM i to make a better attempt at retrieving a FQDN.
    .
    To obtain the fix:
    Install build 20091223 or later
    

Temporary fix
