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

[Jiri Locker (JIRA)]

    [ https://issues.jboss.org/browse/DROOLS-1326?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13307258#comment-13307258 ] 

Jiri Locker commented on DROOLS-1326:
-------------------------------------

So what I did is that I removed the 1st solver, which only does a part of CH. Then I took the 2nd solver running with FAST_ASSERT, I let it do the whole CH (740 steps total), and I limited its LS to 1233 steps, which should lead to the same state as the original 1st and 2nd solvers without any modifications. Then I left the 3rd solver with NON_INTRUSIVE_FULL_ASSERT to solve for 30 minutes, supposedly starting from the same state, but it didn't fail.

The output with the described modifications looks like this:
