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!
Best regards,
