I checked all the subclasses with 5K iterations multiple times. The test is forcing a number of results to be returned via the capped results query, so it will always return a number of results that will result in doing an exact query. Why do you think it will be flaky? -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
