Mario Fusco resolved DROOLS-1029.
---------------------------------
    Resolution: Cannot Reproduce Bug


I tried to reproduce the issue you reported with the following test case, but it works for me. In case you're able to provide a different test case reproducing this problem, please attach your reproducer here and reopen this ticket.

{code}
    @Test
    public void testCheckExpirationWithAccumulateOnSameTimeWindow() {
        // DROOLS-1029
        String drl = "import " + SimpleEvent.class.getCanonicalName() + "\n" +
                     "declare SimpleEvent\n" +
                     "    @role( event )\n" +
                     "    @expires( 10s )\n" +
                     "end\n" +
                     "\n" +
                     "rule R when\n" +
                     "   accumulate(SimpleEvent() over window:time( 10s ); $count:count(); $count>1 )\n"  +
                     "then\n" +
                     "   System.out.println(\"count = \" + $count);" +
                     "end";

        KieSessionConfiguration sessionConfig = KnowledgeBaseFactory.newKnowledgeSessionConfiguration();
        sessionConfig.setOption( ClockTypeOption.get( ClockType.PSEUDO_CLOCK.getId() ) );

        KieHelper helper = new KieHelper();
        helper.addContent( drl, ResourceType.DRL );
        KieBase kbase = helper.build( EventProcessingOption.STREAM );
        KieSession ksession = kbase.newKieSession( sessionConfig, null );
        PseudoClockScheduler clock = ksession.getSessionClock();

        ksession.insert(new SimpleEvent("1", 0L));
        ksession.insert(new SimpleEvent("2", 0L));
        ksession.fireAllRules();

        // Session should only contain the events we just inserted
        assertEquals( 2, ksession.getFactCount() );

        clock.advanceTime( 15, TimeUnit.SECONDS );
        ksession.fireAllRules();

        // Events are expired so session should be empty now
        assertEquals( 0, ksession.getFactCount() );

        ksession.dispose();
    }

>          Issue Type: Bug
>          Components: core engine
>    Affects Versions: 6.3.0.Final

> I have declared an event with an attribute @expires 10m.
> I have a rule which accumulates these events over window:time(10m).
> With this setup, the number of facts keeps growing in WM beyond 10 minutes of corresponding facts.
> If I set the the expires to less, say 9 minutes, they do expire after 9 minutes, and if I set the expires to 11 minutes, they do expire after 11 minutes.
> So it looks like matching @expires and accumulate time window void any expiry. I couldn't find anything on this in the documentation and please correct if this has been reported already.
