Lily Wei updated DERBY-4771:
----------------------------

    Attachment: rjall.out

Thanks Kristian for great work!!! When does the invalidation request be performed now? Does
it control in IndexStatisticDaemon? I run the Suites.all with the following comment in windows
'java -client -Dderby.tests.trace=true -Dderby.language.disableIndexStatsUpdate=t
rue -Dderby.language.logIndexStatsUpdate=true -Dderby.language.traceIndexStatsUp
date=both -Dderby.storage.indexStats.auto=true -Dderby.storage.indexStats.log=tr
ue -Dderby.storage.indexStats.trace=both -XX:MaxPermSize=192M -Xmx1024M -Xms512
M -DderbyTesting.oldReleasePath=c:/derby/oldrelease/jars junit.textui.TestRunner
 org.apache.derbyTesting.functionTests.suites.AllPackages 2>&1 | tee rjall.out  
As expected, some tests fail because of standard out is different than canon. I will run it
again and set -Dderby.storage.indexStats.trace to dblog instead. Is dblog the best name? I
think it is very Derby orientated and might not be that intuitive to new Derby user. How about
just "log"?
I am attaching the output just for reference.
