        Description

        A DESCRIPTION OF THE PROBLEM :
        We have been setting SO_LINGER to 0 so we can close a secure connection promptly. This has been working well for us in JDK 9 and JDK 10. But it stops working when we move to JDK 11. In JDK 11, it can take 30 seconds to one minute to have a socket really closed (close_notify sent) even with SO_LINGER set to 0.

        Comparing source code of JDK 10 and JDK 11, it seems that the SO_LINGER option is ignored in JDK 11.


        CUSTOMER SUBMITTED WORKAROUND :
        We have done quite some research but can't find a workaround.

        FREQUENCY : always
