because of an inner class. After extracting it the build
no longer fails.

81711d551f fix performance regression 
The last improvement of memory usage introduced a performance
regression. The ingestion performance dropped by 50%-80%, because
for every inserted entry the Tags were created inefficient.

f2868fcc1b reduce memory footprint: old generation by 100 MB 
This reduces the size of the old generation by 100MB (300MB down to
200MB). Unfortunately the total JVM size didn't change and is still
512MB.

Doc stores the path as byte array instead of Path.
