Review comment:
So its subtle. `getJWTTokenExpiration` is called from the following code:
```
try {
validateToken(token);
} catch (final UnknownTokenException e) {
/* if token permissiveness is enabled we check JWT token expiration
when the token state is unknown */
if (permissiveFailureEnabled && StringUtils
.containsIgnoreCase(e.toString(), "Unknown token")) {
return getJWTTokenExpiration(token);
} else {
throw e;
}
}
```
What this means is that originally the `validateToken` call would throw
`UnknownTokenException`. With this change, the `UnknownTokenException` is
caught and `getJWTTokenExpiration` is called. If `getJWTTokenExpiration` fails,
the code throws `IllegalArgumentException`
So it has the same effect of converting `UnknownTokenException` to
`IllegalArgumentException` based on the settings introduced.

> While unlikely, it's possible that the TokenStateService may be presented
> with a token, for which it has no state, but which can be verified as a valid
> (origin, expiration, etc...) token. In these cases, rather than rejecting the
> token for lack of server-managed state, the token's state should be recorded,
> and the associated operation permitted.
