Mario fixed and backported the jira issue to 5.3, so it's likely that this issue has
been fixed.

My application has to monitor when a magnetic contact is activated and when it is contact
released event has to be retracted. And viceversa. Here is my rule and the big null
pointer I have. Any helps will be very appreciated! Thank you a lot!!
rule "contact activated vs contact released" salience 0 no-loop true
when
$contact_activated : Event(type == EventType.CONTACT_ACTIVATED) ||
$contact_released : Event(type == EventType.CONTACT_RELEASED)
then
if($contact_activated!= null) {
retract($contact_activated);
} else {
retract($contact_released);
}
end
and
I have
java.lang.NullPointerException
