>  {code}
> *How to reproduce it locally?*
> Replace the last tableCache.evict call of testPartialTableCacheWithOverrideAndDelete to System.out.println(tableCache.size()).
> You will see that the cache size is 2 even before the cleanup therefore the next GeneriTestUtils.waitFor is useless (it doesn't guarantee that the cleanup is finished).
> *Fix:*
> I propose to call the cleanup sync with using the Impl class instead of the interface. It simplifies the test but still validates the behavior.
