Error description

  • Error Message: This issue is reported on AIX-JDK-142.
    Problem Scenario:
    In any java application if we try to set any option (like
    TCP_NODELAY) for the socket fd which is already close
    (PreClose() or Dup) then JVM will throw following exception:
    Exception in thread "main" java.net.SocketException: A system
    call received a parameter that is not valid.
            at java.net.PlainSocketImpl.socketSetOption(Native
    Method)
            at
    java.net.PlainSocketImpl.setOption(PlainSocketImpl.java:292)
            at java.net.Socket.setTcpNoDelay(Socket.java:805)
            at Foo.main(Foo.java:40)
    But this exception says that parameter pass to the
    socketSetOption() is not valid, but actual scenario is of socket
    reset, which can create a confusion for user and is not
    directing them to the correct direction to diagnose the problem.
    .
    Stack Trace: N/A
    .
    

Local fix

  • We changed this exception error message according to the
    IEEE-Open Group Base Specifications for setsockopt() subroutine
    (AIX API adhere to these specifications).
    
    http://www.opengroup.org/onlinepubs/009695399/functions/setsocko
    pt.html
    After making the changes in JVM is will show following exception
    message:
    Exception in thread "main" java.net.SocketException: The
    specified  option is invalid at the specified socket level or
    the socket has been shut down.
    This message gives the pretty much clear idea on the possible
    reason of failure which can direct customer to the correct
    direction to diagnose the failure. So I modified the code
    accordingly so that it should throw the correct message to the
    user.
    

Problem summary

  • AIX-JDK is not returning the correct message for socket
    exception.
    

Problem conclusion

  • This defect will be fixed in:
    1.4.2 SR13-1 (AIX)
    .
    JDK-CL code is updated so that it must return the correct
    message for socket exception.
    .
    To obtain the fix:
    Install build 20090525 or later
    

Temporary fix
