2:46 a.m.
Sometimes (I am not sure what the actual reason is yet ) I get following NPE when I try to
deserialize my ksessions:
java.lang.NullPointerException
at
org.drools.common.ConcurrentNodeMemories.getNodeMemory(ConcurrentNodeMemories.java:63)
at
org.drools.common.AbstractWorkingMemory.getNodeMemory(AbstractWorkingMemory.java:1034)
at
org.drools.rule.SlidingTimeWindow$BehaviorExpireWMAction.<init>(SlidingTimeWindow.java:460)
This is not a new problem, I found an old post on the mailing list, that describes the
same here: (but unfortunately without any answers)
http://drools.46999.n3.nabble.com/rules-users-5-5-0-Final-persistence-to-...
Apparently it's got something to do with slidingTime in one rule, but as it does not
always occur - am I quite puzzled.
Any Ideas or Workarounds?

Which version are you using?
Could you try 5.6.0-SNAPSHOT?
Thanks

Wohoo... I finally tried 5.5.6 =(
1. Comments with # do not work anymore, only // works
2. Problem with CRON Timer
10:50:50.827 [main] WARN o.d.t.impl.DefaultTimerJobInstance - Unable to execute timer

I could fix the first problem by replacing all comments, but the second gives me headache
- bug in 5.6.0 ? The rule looks like this:
rule "set environment night"
no-loop
timer (cron:0 30 20 1/1 * ? *)
when
$env : Environment ( )
then
modify ( $env ) { state = EnvironmentState.NIGHT }
end
-> No Idea if my previous problems still exists....must first get 5.6.0 to work with my
rules at all...

Yes, # for comments had actually been deprecated for a while.
# is now used for inline casts, so I'm afraid you'll have to replace the
comments
As for the other issue.. this is more serious, but should be fixable.
Can you post the full stack trace? And, if possible, a reproducer? :)

Good catch, it is indeed a 5.6 regression.
Fixed, the pull request should be merged momentarily.
