> We have had some issues (e.g. OAK-3634) which put incorrect entry in the some cache.
Currently, the only way to clean cache is to restart the instance (and remove persistent cache
files if configured).
> So, it might be useful to expose some jmx to invalidate cache without restarting the
instance. As a first step, I think we can clean all caches (which is equivalent to current
setup but without restart). We can later expose invalidation methods for specific cases (say,
{{cacheType, path, rev}} as applicable).
