Knut, thank you, updating the statistics helped very much! 

(I added a tunable stats updater for different servers to my software)

///
This section in the tuning guide lists when the index cardinality
statistics are automatically updated:
http://db.apache.org/derby/docs/10.5/tuning/ctunstats57373.html

Additionally, there is a system procedure that can be used to update the
statistics manually:
