[jboss-jira] [JBoss JIRA] (DROOLS-1097) Loading Session and running rules re-executes all rules

Loading Session and running rules re-executes all rules -------------------------------------------------------- Key: DROOLS-1097 URL: https://issues.jboss.org/browse/DROOLS-1097 Project: Drools Issue Type: Bug Components: core engine Affects Versions: 6.3.0.Final Environment: Mac OS 10.10.5, Eclipse Mars Release, Java 1.8, Drools 6.3.0.Final Reporter: Artur Kronenberg Assignee: Mario Fusco Attachments: test-standalone.zip This is possibly directly related to: (or rather that one relates to this one) https://issues.jboss.org/browse/DROOLS-1093 The situation: * Create a session with 2 rules. 1 Rule expires facts that are in the working memory by retracting them. * Add the ExpiryFact to expire some facts * Execute all rules -> X facts get expired * dispose the existing session * re-load the session * without adding more facts to the working memory, run all rules * The session re-executes more rules and retracts things from memory Now there seem to be 2 problems with this: 1. The session does not remember what facts it expired. So it will delete more infos, that are still "somewhere". When re-loading the session from the database, we will see an NPE 2. Surely since it already ran the rules against the Expiry fact, it should not run them again. I will attach a unit test ExceptionTest#testRulesAreFiredTwice with this bug. Let me know if this can be worked around please and/or if there are any more questions. Thanks, Artur
