124 private static final int KDC_OPT_RENEWABLE_OK = 0x00000010; The position of renewable-ok is 27. I think the mask is 0x0000,0100. 125 private static final int KDC_OPT_FORWARDABLE = 0x40000000; The position of FORWARDED is 2. I think the mask is 0x2000,0000. Personally, I would like to use (1<<(31-n)) as the mask. It looks more straightforward.
