Retracting events using PseudoClockScheduler causes ClassCastException ---------------------------------------------------------------------- Key: JBRULES-2299 URL: https://jira.jboss.org/jira/browse/JBRULES-2299 Project: Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-core, drools-core (fusion) Affects Versions: 5.1.0.M1 Reporter: Maciej Prochniak Assignee: Mark Proctor When job is scheduled e.g. in sth like not A(this after [1s,10s] $a) and relevant event is retracted from working memory, the job should be removed. However, PseudoClockScheduler usues queue containing wrappers for job (ScheduledJob), and remove method tries to remove job without this wrapper which causes: java.lang.ClassCastException: org.drools.common.Scheduler$DuractionJob incompatible with org.drools.time.impl.PseudoClockScheduler$ScheduledJob at org.drools.time.impl.PseudoClockScheduler$ScheduledJob.compareTo(PseudoClockScheduler.java:188) at java.util.PriorityQueue.remove(PriorityQueue.java:355) at org.drools.time.impl.PseudoClockScheduler.removeJob(PseudoClockScheduler.java:121) at org.drools.common.Scheduler.removeAgendaItem(Scheduler.java:62) at org.drools.common.DefaultAgenda.removeScheduleItem(DefaultAgenda.java:451) at org.drools.common.ScheduledAgendaItem.remove(ScheduledAgendaItem.java:198) at org.drools.reteoo.RuleTerminalNode.retractLeftTuple(RuleTerminalNode.java:289) at org.drools.reteoo.SingleLeftTupleSinkAdapter.doPropagateRetractLeftTuple(SingleLeftTupleSinkAdapter.java:131) at org.drools.reteoo.SingleLeftTupleSinkAdapter.propagateRetractLeftTuple(SingleLeftTupleSinkAdapter.java:42) at org.drools.reteoo.NotNode.retractLeftTuple(NotNode.java:276) at org.drools.reteoo.ObjectTypeNode.retractObject(ObjectTypeNode.java:234) at org.drools.reteoo.EntryPointNode.retractObject(EntryPointNode.java:195) at org.drools.common.AbstractWorkingMemory.retract(AbstractWorkingMemory.java:1207) at org.drools.common.AbstractWorkingMemory.retract(AbstractWorkingMemory.java:1161) at org.drools.impl.StatefulKnowledgeSessionImpl.retract(StatefulKnowledgeSessionImpl.java:237) at pl.touk.droolsTest.PseudoSchedulerRemoveJobTest.testRule(PseudoSchedulerRemoveJobTest.java:61) ...more Solution would be probably to wrap job which should be removed -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
