When I run sample code of section "starting a ruleflow from a rule" in documentation (https://nheron.gitbooks.io/droolsonboarding/content/gettingStarted/lesson...), the output sequence is different from the screenshot. But when I switched to drools version to 6.4.0 Final, the output sequence was extactly same with screenshot.
