        Description

        FULL PRODUCT VERSION :
        java version "1.8.0_101"
        Java(TM) SE Runtime Environment (build 1.8.0_101-b13)
        Java HotSpot(TM) 64-Bit Server VM (build 25.101-b13, mixed mode)


        ADDITIONAL OS VERSION INFORMATION :
        Linux <hostname> 4.2.0-42-generic #49-Ubuntu SMP Tue Jun 28 21:26:26 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

        A DESCRIPTION OF THE PROBLEM :
        From sun/security/jgss/krb5/SubjectComber.java, method findAux(), upon finding an expired ticket:

        if (!ticket.isCurrent()) {
        ...
             ticket.destroy();
             if (DEBUG) {
               System.out.println("Removed and destroyed "
               + "the expired Ticket \n"
               + ticket);
        ...

        The problem is that after ticket.destroy() call all methods of ticket object, including toSttring(), throw IllegalStateException, so if DEBUG == true, System.out.println() throws IllegalStateException.

        For toString() throwing IllegalStateException makes no sense; we always want to print out the ticket info, expired or not.

        Since there is no proper handling of IllegalStateException, the ticket does not get renewed.

        Suggested fix: remove the following lines from from toString() method of javax.security.auth.kerberos.KerberosTicket class:

        if (destroyed)
            throw new IllegalStateException("This ticket is no longer valid");
