I reply in english because my spanish is terrible.
You are right.
This is a warning message that the Open CMIS java libraries write during the extraction. You can ignore the message for your needs (it does not cause problems).
The extraction job has been completely rewritten, to solve this issue and to have a relevent improvement of the duration. Today the extraction is too slow for huge repositories. 😉
