Subject [jira] [Commented] (OAK-7801) CompositeNodeStore.merge() may trigger conflicting branches

Tomek Rękawek commented on OAK-7801:
------------------------------------

[~mreutegg] - yes, it looks good. Hopefully now the {{CompositeNodeStore#merge()}} is as simple
as possible.

> This issue only affects a CompositeNodeStore with a global DocumentNodeStore. The merge()
may trigger the creation of two conflicting DocumentNodeStore branches, which then fails the
merge operation even though there is no real conflicting change. This issue does not happen
with 1.8 or earlier because those releases keep changes introduced by commit hooks in memory.
