> This test only exists in branches 1.4 and older and was introduced as part of 
> OAK-5238. The test fails every now and then with (stack trace from 1.4):
> {noformat}
> java.lang.IllegalStateException: This builder does not exist: child-0

> Please note that it fails more likely when the update.limit is set to 100, 
> which is the case for the maven build.
> I also ported the test to 1.6 and running it with the new segment-tar looks 
> OK. I don't know if this is because the copy-on-write or the segment-tar 
> implementation is different than in 1.4. 
> The affected versions are currently only set to 1.4.18, because there were no 
> releases off the 1.2 and 1.0 branches since OAK-5238 was backported.
