Erick Erickson commented on SOLR-7836:
--------------------------------------
I ran the StressTestReorder yesterday with the changes and didn't get it to
fail for 50 runs on my laptop. Then last night I kicked off a 1,000 repetition
run on my home machine and... didn't remember to look this morning before I
left home.
So I'm pretty sure that StressTestReorder is OK with the latest patch, I'll
look tonight to be sure.
[[email protected]] I saw what I think is the same failure on the dev list
from a Jenkins build last night and AFAIK the changes are still in there.
