No, I am just talking about documenting existing behavior, ex:

For these methods, I would add:

This method returns null if the ticket has been destroyed.

For other methods that already throw ISE, I would add:

@throws IllegalStateException if the ticket has been destroyed

I also noticed that many of the methods do not declare that they throw IllegalStateException when destroyed, so I think a general cleanup of the specification would be a good thing to do as part of this issue for JDK 9.
