Thomas Mueller commented on OAK-333:

> Key: OAK-333
> URL: https://issues.apache.org/jira/browse/OAK-333
> Project: Jackrabbit Oak
> Issue Type: Bug
> Components: mongomk
> Affects Versions: 0.5
> Reporter: Mete Atamel
> Assignee: Thomas Mueller
> Priority: Minor
> Fix For: 0.19
>
> Attachments: NodeNameLimitsTest.java, OAK-333.patch
>
>
> In an infinite loop try to add nodes one under another to have N0/N1/N2...NN.
> At some point, the current parent node will not be found and the current
> commit will fail. I think this happens when the path length exceeds 1000
> characters. Is this enough for a path? I was able to create this way only 222
> levels in the tree (and my node names were really short N1, N2 ...)
> There's an automated tests for this: NodeExistsCommandMongoTest.testTreeDepth
