The comment is confusing to me. Per the getRenewTill() specification, does
"getRenewTill() == null" means the ticket is non-renewable (destroyed)?
This is a bug of MIT krb5's kdc implementation, which wrongly issues a
renewable ticket without the renew_till field. We will have to deal with it.
getRenewTill()'s spec says null is return if the ticket is non-renewable
(destroyed), but has not said it does not return null if it's renewable. Of
course, it's an error case but I mean the spec has not enforced it.
I can enhance the comment to something like "Renewable ticket without renew_until.
This is illegal and let's ignore it".
The new comment looks more reasonable to me. Please note that you have
two update calling getRenewTill(). Otherwise, looks fine.

This is a MIT/krb5 bug [1], but we will accept it anyway. Also, renew such a
ticket is now a no-op because the lifetime will not be extended anyway.
New test included.
Thanks
