Local fix

Problem summary

• The problem is caused when a live connection with AIX socket is
  terminated with a TCP RST signal. AIX implementation is such
  that the socket resources in the kernel layer are cleared up by
  the kernel upon receiving the RST. This error is converted into
  an unexpected SocketException which is not handled properly by
  the JCL code and wrapped in an Error.
  

Problem conclusion

• This APAR will be fixed in the following Java Releases:
     7    SR8 FP10       (7.0.8.10)
     7 R1 SR2 FP10       (7.1.2.10)
  
  The JDK has been updated to reaturn a null instead of
  throwing SocketException.
