[jboss-jira] [JBoss JIRA] (DROOLS-886) ClassCastException when kcontainer.updateToVersion() with sliding window rule running (with fix for DROOLS-881 and DROOLS-883)

Mario Fusco commented on DROOLS-886:
------------------------------------

Neither me nor Petr have been able to reproduce this CCE against latest drools 6.4.0-SNAPSHOT. Conversely Petr reported that he has been able to reproduce that CCE against drools 6.3.0.CR1. Since that release doesn't have all the fixes I pushed during the last days, this confirms my impression that the CCE you reported has been solved as side effect of one of those fixes.

> When you call kcontainer.updateToVersion() while running sliding window rules, you will the following Exception.
> I tested it with master(6.4.0-SNAPSHOT), and I guess it includes the fix for  DROOLS-881 and DROOLS-883. However the issue still occurs.
