Reinis Vicups updated JBRULES-3416:
-----------------------------------
Description:
Given rules lead to (presumed) memmory corruption in some data scenarios:
{code}
package de.orbitx.accumulatetesettest;
import de.orbitx.accumulatesettest.DomainObject;
import de.orbitx.accumulatesettest.Foo;
import de.orbitx.accumulatesettest.Bar;
import de.orbitx.accumulatesettest.Counter;
global DomainObject aggregator;
rule "reward Bar consolidation"
when
$leftFoo : Foo($leftBar : bar, $leftId : id, $leftInterval : interval)
$rightFoo : Foo(bar == $leftBar, id != $leftId, interval.getStart() < $leftInterval.getStart())
eval($leftFoo.getInterval().getStart() - $rightFoo.getInterval().getStart() < 4)
then
insertLogical(new Counter(1));
System.out.println("Rewarding leftFoo:" + $leftFoo + " rightFoo:" + $rightFoo);
end
rule "softConstraintsBroken"
when
$softTotal : Number() from accumulate(
Counter(counterType == 2, $counterType : counterType),sum($counterType))
$positiveSoftTotal : Number() from accumulate(
Counter(counterType == 1, $counterType : counterType),sum($counterType))
then
aggregator.setValue($softTotal.intValue() - $positiveSoftTotal.intValue());
end
{code}
For instance:
{code}
Foo(id:1, bar:Bar: 0, baz:null, int:Int(start:3, duration:0))
Foo(id:2, bar:Bar: 0, baz:null, int:Int(start:1, duration:0))
Foo(id:3, bar:Bar: 1, baz:null, int:Int(start:4, duration:0))
Foo(id:4, bar:Bar: 1, baz:null, int:Int(start:2, duration:0))
{code}
session.fireAllRules lead to aggregator.getValue of -2 and following activations
{code}
Rewarding leftFoo:Foo(id:3, bar:Bar: 1, baz:null, int:Int(start:4, duration:0)) rightFoo:Foo(id:4, bar:Bar: 1, baz:null, int:Int(start:2, duration:0))
Rewarding leftFoo:Foo(id:1, bar:Bar: 0, baz:null, int:Int(start:3, duration:0)) rightFoo:Foo(id:2, bar:Bar: 0, baz:null, int:Int(start:1, duration:0))
{code}
when swapping Bars of Foo 1 and Foo 3:
{code}
Foo(id:1, bar:Bar: 1, baz:null, int:Int(start:3, duration:0))
Foo(id:3, bar:Bar: 0, baz:null, int:Int(start:4, duration:0))
{code}
session.fireAllRules lead to aggregator.getValue of -1 and following activations
{code}
Rewarding leftFoo:Foo(id:3, bar:Bar: 0, baz:null, int:Int(start:4, duration:0)) rightFoo:Foo(id:2, bar:Bar: 0, baz:null, int:Int(start:1, duration:0))
{code}
Second activation for the Foo 1 and Foo 4 does not happen, thus Geoffreys assumption is that working memory is corrupted.
