Local fix

Problem summary

• The existing implementation assumes that the system always has
  127.0.0.1 as IPv4 loopback address (IPv4 loopback interface).
  This loopback address is used by the selector implementation
  during initialization phase.
  

Problem conclusion

• The JVM is updated to use system's default loopback interface
  instead.
  .
  This APAR will be fixed in the following Java Releases:
     6    SR16 FP3  (6.0.16.3)
     7    SR8 FP10  (7.0.8.10)
     6 R1 SR8 FP3   (6.1.8.3)
     7 R1 SR2 FP10  (7.1.2.10)
