Alex Parvulescu commented on OAK-654:
-------------------------------------
Another case of failing preconditions I ran into by mistake is the
_org.apache.jackrabbit.test.api.SerializationTest_ test [0].
It appears the cleanup part from AbstractJCRTest#cleanUpTestRoot is unable to
finish properly.
I find this interesting (even though the _SerializationTest_ test is marked as
ignored currently) because the cleanup method is called from all the JCR tests.

> MapBranch size preconditions can fail
> -------------------------------------
>
> Key: OAK-654
> URL: https://issues.apache.org/jira/browse/OAK-654
> Project: Jackrabbit Oak
> Issue Type: Sub-task
> Components: segmentmk
> Reporter: Alex Parvulescu
> Priority: Minor
>
> One example is the UserQueryTest#testAny test where the size expectations can
> fail, a value always bigger than _BUCKETS_PER_LEVEL(32)_ is expected but here
> the value is _4_.
> afaik this happens on the teardown, so it may be related to a big number of
> deletes.
