Problem summary

    select() operations are not synchronized properly. Because of
    this, there can arise a narrow timing window where in the
    interestOps will remain unupdated.
    

Problem conclusion

  • This defect will be fixed in:
    6.0.0 SR13
    6.0.1 SR5
    7.0.0 SR4

    synchronization is introduced to maintain consistency in the
    interestOps of a Channel with the target selector.
