--------------------------------------

Thanks, [~cnauroth] - that is helpful!
I know that I used to be able to do that - something must have changed.

Manual options is great though!

> Current implementation of getPropsWithPrefix uses the Configuration.iterator() method.
This method is not threadsafe.
> This patch will reimplement the gathering of properties that begin with a prefix by using
the safe getProps() method.
