Kristian Waagan commented on DERBY-5097:
----------------------------------------
I can't reproduce on my machine with a sane build at least.
Did you use sane or insane?
How many cpus/cores on the machine?
If possible, can you add a timeout value to the IndexStatsUtil instance on line
142? For the sake of ruling out "delayed istats", the timeout value can be
rather high (ten seconds?).
