Marcel Reutegger resolved JCR-1884.
-----------------------------------

       Resolution: Fixed
    Fix Version/s: 1.6.0

Optimized initialization of parents cache. The time dropped from 40 minutes to 
90 seconds for the above mentioned index. Initialization is now done in a 
background thread, which means the startup of the repository is not delayed 
anymore.

Fixed in revision: 721495

> CachingIndexReader.initializeParents() does not scale well with large indexes

> This is way to much, needs optimization and should be done in a background
