[jboss-jira] [JBoss JIRA] (DROOLS-1326) Stateful working memory regression OCT-2016: nurserostering long_hint01.xml

[Geoffrey De Smet (JIRA)]

    [ https://issues.jboss.org/browse/DROOLS-1326?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13323888#comment-13323888 ] 

Geoffrey De Smet commented on DROOLS-1326:
------------------------------------------

+1 Not a regression
The reason we spotted it is because the TurtleTests are a little bit random (despite their random seeds being fixed): depending on cpu time, the first solver may do a step more or a step less, which affects the starting solution of the second solver (and likewise third solver).

Maybe we should give the turtle tests a random seed to increase the test coverage?
