Kathey Marsden commented on DERBY-4116:
---------------------------------------

I made the change recommended by Mike and committed revision 760497 to trunk.  I will wait
for clean nightly results and backport to 10.5. Meanwhile I'll leave this issue open.  Thanks
for the reviews!

> When SYSCS_UTIL.SYSCS_UPDATE_STATISTICS is run, it doesn't update the store estimated
row count.  The program oldSelectivity.java attached to DERBY-3955 shows that the statistics
are not updated.
