[jboss-jira] [JBoss JIRA] (DROOLS-2194) ClassCastException after kiescanner scanNow() method

Pedro Almeida created DROOLS-2194: ------------------------------------- Summary: ClassCastException after kiescanner scanNow() method Key: DROOLS-2194 URL: https://issues.jboss.org/browse/DROOLS-2194 Project: Drools Issue Type: Bug Affects Versions: 7.5.0.Final Reporter: Pedro Almeida Assignee: Edson Tirelli I need to add and remove rules in runtime, without losing facts. I'm achieving this by manipulating a kJar on my .m2 folder by adding and removing rules. The scanner is attached and the scanNow() method is invoked whenever a change occurs. But whenever I load a rule back (say on rule YYY), I get errors on (XXX), seems like it has to do with accumulates and can occur on various rules, something like: 18:13:15,354 SEVERE
