Knut Anders Hatlen commented on DERBY-6336:
-------------------------------------------
I ran the test with {{derby.storage.indexStats.log=true}} and saw that the
index statistics daemon does kick in during the test. I don't know if that is
what's causing this failure, but I think it makes sense to disable the index
statistics daemon for this test. Since the test needs to control exactly when
statements are recompiled in order to run reliably, it is imaginable that the
index statistics daemon confuses the test if it kicks in and changes the index
cardinality statistics at a bad time.
