Problem summary

  length (including null string terminator) where as another
  network application in zOS , DynamicXCF expect the network
  interface cardname of 17 bytes (which is 16 bytes excluding the
  null string terminator).
  

Problem conclusion

     6    SR16      (6.0.16.0)
     7 R1 SR1       (7.1.1.0)
     6 R1 SR8       (6.1.8.0)
     7    SR7       (7.0.7.0)
  .
  The JDK has been updated to allow network interface card names
  upto 17 bytes on zOS platform.
