>> [JDK-8328638](https://bugs.openjdk.org/browse/JDK-8328638) introduced a new boolean option, `com.sun.security.ocsp.useget`. We use the usual `Boolean.parseBoolean` to convert it from String to boolean value, which works correctly for `false` and `true` as boolean values. However, any string that is not `true` would be treated as `false`. Which means that if users mistype the value, they would get a `false`, which is a non-default value, which is against the spirit of the JDK-8328638.

Update copyright date on SimpleOCSPServer. Otherwise, looks good!
