-------------------------------------
Not Enough Information?
We commented in "Steps to Reproduce".
1. Setting Project (described in detail below)
2. Repeatedly send Rest call using SoapUI
3. Change window time and hot deploy in 1m(window time)
4. Check Count. But.. return wrong result count. (rower or higher)
==================================================

then

end
rule "Rule-s1-2"
when
Number( $result3 : intValue) from accumulate(AnEvent( $src: source, $wrd: word) over
window:time(10s) from entry-point EP1, count( $src ))
then
System.out.println(" !!@-------> Result-s1-2 (CNT): " + $result3);
end
Change Rule Containing Window Time
-----------------------------------
Key: DROOLS-853
URL: https://issues.jboss.org/browse/DROOLS-853
Project: Drools
Issue Type: Bug
Components: core engine

I tested rule contain sliding window.
But when i deployed the rule to change window time,

I attached trace result.
