Code review request: 8000653: SPNEGO tests fail at context.getDelegCred().getRemainingInitLifetime(mechOid)

[Wang Weijun]

Hi Valerie

Please review this code change

   http://cr.openjdk.java.net/~weijun/8000653/webrev.00/

The reason is that if a SPNEGO GSSContext is established with krb5 underneath, its getDelegCred() only returns one krb5 cred element. I need to add more for mechs that are "compatible" with this mech. Currently it's only spnego so I hard code it.

This change seems to have made the following lines in GSSContextImpl.initSecContext(stream,stream) obsolete, but I'll keep them unchanged for safety.

    try {
        credElement = myCred.getElement(mechOid, true);
    } catch (GSSException ge) {
        if (GSSUtil.isSpNegoMech(mechOid) &&
            ge.getMajor() == GSSException.NO_CRED) {
            credElement = myCred.getElement
                (myCred.getMechs()[0], true);
        } else {
            throw ge;
        }
    }

All regression tests run fine.

Thanks
Max
