Claus Ibsen commented on CAMEL-13425:
-------------------------------------

Mind that even if you invalidate a cache then many of the property placeholders 
are only looked up once on startup etc. So if your use-case is that if you 
modify a application.properties file (for instance) and then invalidate cache, 
then all of its property keys/placeholders are automatic magically updated in 
Camel. Then that wont work, and its not designed to do so.

> Add possibility to invalidate cache for PropertiesComponent

> Currently I can only enable/disable cache for PropertiesComponent.
> I'd like to be able to enable caching, but programmatically invalidate cache 
> on demand.
> This should be rather simeple to implemet, something like:
> {code:java}
> public void invalidateCache() {
>   this.cacheMap.clear();
> }
> {code}
