Why is my timeout of 15 minutes not working for the resetContainerPassword() method, using the Knox SDK?

For the ContainerConfigurationPolicy.resetContainerPassword() API method, in order to use the second timeout parameter, you must not have null as the first parameter

The first parameter of resetContainerPassword() API method should be the key that was given during container creation. We commonly call it as "reset password token". Without this, the API timeout has no effect, and the user is prompted to reset their password immediately.
