Hmmm, strange... would you be able to share your junit test? If so, could
you please open a JIRA and attach the test?
Thanks,
Edson

Hi folks!
First time in this mailing-list, with very little experience in Drools (Fusion,
regarding CEP).
I hope that someone could help me out J
I've being investigating about this issue and I'm not getting any answer.
Here's the problem:
I've got a DRL file with a simple rule:
rule
when
$offline : Event( code == 101, $offlineLane : lane ) from
entry-point incoming
not ( $online : Event(code == 102, lane == $offlineLane, this
after [0s,3m] $offline ) from entry-point incoming )
then
// some code here
end
What I want is: when there's an offline for more than 3 minutes *without* any
online event (meanwhile), that execute the rule.
I've got JUnits, with Drools configured with STREAM mode and PSEUDO clock.
All is good in JUnit world except in this testcase:
· Insert an offline event (workingMemoryEntryPoint.insert( offlineEvent
);)
· Clock advances 2m50s (clock.advanceTime(2,TimeUnit.MINUTES
);clock.advanceTime(50, TimeUnit.SECONDS );)
· Insert an online event (workingMemoryEntryPoint.insert( onlineEvent
);)
· Clock advances 0m15s (clock.advanceTime(15,TimeUnit.SECONDS );)
· Assertion error: the rule runs when it shouldn't (online event
cancels offline event).
I've got no clue about this but I have some more interesting info:
· When clock advances 0m15s, there's an NPE on a LinkedList:
java.lang.NullPointerException
at org.drools.util.LinkedList.remove(LinkedList.java:113)
at org.drools.common.Scheduler$DuractionJob.execute(Scheduler.java:71)
at
org.drools.time.impl.PseudoClockScheduler$ScheduledJob.call(PseudoClockScheduler.java:219)
at
org.drools.time.impl.PseudoClockScheduler.runCallBacks(PseudoClockScheduler.java:168)
at
org.drools.time.impl.PseudoClockScheduler.advanceTime(PseudoClockScheduler.java:130)
· I haven't any code/rule that retracts events (I shouldn't have it for
this case, right?)
· I've tried Drools 5.0.1 and 5.1.0.M1, with the same results
· The issue causing NPE, I've found an old issue regarding Drools 3.0.4
and the bug was corrected in 3.0.5
(https://jira.jboss.org/jira/browse/JBRULES-455)
· I think that someone wrote about this error (in Drools 5) but I don't
have the link to it.
Thanks In Advance!
