window:length windows retaining events when they shouldnt
---------------------------------------------------------

                 Key: JBRULES-3075
                 URL: https://issues.jboss.org/browse/JBRULES-3075
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-core (fusion)
    Affects Versions: 5.2.0.CR1
         Environment: win64, jdk 6u24
            Reporter: Radai Rosenblatt
            Assignee: Mark Proctor
         Attachments: drools length window bug.zip

using the following DRL:

package contrived.example

import contrived.example.EventWithTimestamp

declare EventWithTimestamp
    @role(event)
	@duration( duration )
    @timestamp( timestamp )
end

rule "no event in window"
when
    not EventWithTimestamp (someProp=="whatever") over window:length(3) from entry-point "Event Stream"
then
    System.err.println("retract");
end

if we start with an initial matching (someProp=="whatever") event and a fire a long sequence of non-matching events:
{"something else", "something else" ... "something else"}
the rule should fire sometime into the long chain of "something else" events (it should fire after the 3rd such event).
in practice the rule never fires. worse, it also retains all the events in memory ehrn it should only keep the last 3.

to reproduce the issue, simply build the attached maven project (mvn clean install)
