Thomas Mueller commented on OAK-2020:
-------------------------------------

> DocumentNodeStore should provide same NodeState for given (path, revision) 
> whenever a NodeState is obtained from it.

Does it need to be the same object, or would it be enough if it's a different 
object, but the same hash code, and NodeState.equals(..) would return true?

> NodeState view at given version is not stable with DocumentNodeStore

> DocumentNodeStore should provide same NodeState for given (path, revision)  
> whenever a NodeState is obtained from it. This fails in some cases if the 
> Node cache in DocumentNodeStore gets overflown and then the NodeState 
> returned differs. This causes issues like
> # Spurious Commits see - Some commit would fails with conflicts in paths 
> which were not modified in that commit
> # Diff logic would traverse those paths which are not related to changes done 
> in that commit
> More details would be provided in comments below
