APAR status

  • Closed as program error.

Error description

  • Error Message: Connection issues can arise with a socket bound
    to an address returned by InetAddress.getLocalHost(). This is
    when InetAddress.getLocalHost() returns link-local address
    (169.254.*.*). This can especially when the system has multiple
    NICs.
    .
    Stack Trace: N/A
    .
    

Local fix

  • Use InetAddress.getAllByName(localhostname) to get the list of
    Inet Addresses and then pick one which is not a link-local
    address.
    

Problem summary

  • Following Windows 2008 SP2, getaddrinfo() Windows API sorts the
    Addresses and linklocal/APIPA address appears first now.
    

Problem conclusion

  • This defect will be fixed in:
    6.0.0 SR10
    6.0.1 SR1
    7.0.0 SR1
    .
    IBM Java's getLocalHost() is corrected to filter out the
    link-local addresses and return a non-linklocal address to the
    application.
    .
    To obtain the fix:
    Install build 20110921 or later
