SPNEGO tests fail at context.getDelegCred().getRemainingInitLifetime(mechOid)

The JGSS Server.java was enhanced with further debug logs.
.....
         logOutput("Server.impersonateClient: "
                    + "cred.getRemainingInitLifetime(mechOid) after sleep ="
                    + context.getDelegCred().getRemainingInitLifetime(mechOid));
            logOutput("Server.impersonateClient: "
                    + "cred.getRemainingLifetime() after sleep ="
                    + context.getDelegCred().getRemainingLifetime());
...............
With GSS_MECH ="kerberos" tests are fine.
However with GSS_MECH="spengo" the tests are failing
