José Andrés Cordero Benítez commented on OAK-3895:
--------------------------------------------------
I have created a patch to expose the jmx methods to invalidate the 3 available
caches: DiffCache, NodeCache and NodeChildrenCache.
The class DiffCache didn't have a method to invalidate the entries, so I have
added it.

> 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).
