[8u] RFR: 8186576: [2/2] KerberosTicket does not properly handle renewable tickets at the end of their lifetime

[Verghese, Clive]

Hi,

Requesting review for backport of JDK-8186576.

JDK-8186576
JBS Issues : https://bugs.openjdk.java.net/browse/JDK-8186576
Original Change : http://hg.openjdk.java.net/jdk10/jdk10/jdk/rev/fa7582840977
Webrev : http://cr.openjdk.java.net/~alvdavi/webrevs/8186576/webrev.8u.00/


The backport did not apply cleanly, It required changes from JDK-804450. The test case written for JDK-8186576, specifically NullRenewUntil, was requesting renewable tickets, support for which was added in JDK-8044500.
Additionally parts of JDK-8044500 had already been backported.

We could

  1.  Add the required functions and update the tests. Or
  2.  Backport JDK-8044500

I have backported both JDK-8044500 and JDK-8186576.

Other than the usual changes to filenames and copyrights, The patches also needed minor modifications mentioned below.

JDK-8186576

  *   Variable name change in KDC.java
  *   Missing ‘{‘ in the if blocks in KerberosTicket.java
