> Affects Versions: 1.1

> Current reloading process clears current properties and load updated values
> from
> resource reader. If an IO error occurs (or invalid format), the configuration
> gets corrupted and the application becomes unstable.
> It may be better for hot-reload to put loaded values into a temporary
> Properties
> and replace previous values only when reloading is successful.
> It may also allow to use a 'currentlty-reloading' flag in the synchronized
> 'reload' block to avoid blocking threads during a reload (they could access
> safelly the 'old' properties until reload is finished)
