Resolution: Won't Fix

regressions.

> I started with #evictItem but I ended up doing some more tiny changes overall:
> - #evictItem: we can safely refactor the #get -> #remove into a simple
> #remove:
> It appears that the check "cached == data" only applies to shareable nodes. I
> ran the entire jacorabbit-core test suite and the check failed 9 times, out
> of which 3 were related to shareable nodes and the other 6 were just
> comparing to null, in which case we can safely evict the value.
> So if we refactor the method to be consistent with #cacheItem, we can safely
> remove the "==" check. The shareableNodesCache has the shareable nodes info,
> itemCache everything else.
> - #cacheItem doesn't need to check if the key exists, #put already returns
> the info
> - #itemDestroyed does not need to synchronize on itemCache as #evictItems
> already does that
> - ShareableNodesCache#evictAll doesn't need to be synchronized - that is
> already covered by #evictItems with the synchronization on itemCache
> patch follows shortly
