Summary: Wrong type declartion initialization causes an infinite loop when
using property reactivity

Project: Drools
Issue Type: Bug
Security Level: Public (Everyone can see)
Reporter: Mario Fusco
Assignee: Mario Fusco
A drl like the following with DataSample being annotated as @PropertyReactive ends up in
an infinite loop even if it shouldn't.
{{
rule 'Init'
when
$m: Model()
then
System.out.println("Inserting a DataSample");
insert(new DataSample($m));
end
rule "Rule 1"
when
$m: Model()
$d: DataSample(model == $m)
then
System.out.println(drools.getRule().getName());
modify($d){
addValue(Parameter.PARAM_A, 10.0)
}
end
rule "Rule 2"
when
$m: Model()
$d: DataSample(model == $m, $v: values[Parameter.PARAM_A] > 9.0)
then
System.out.println(drools.getRule().getName());
modify($d){

}
end
rule "Data without messages"

Mario Fusco commented on JBRULES-3686:
--------------------------------------
The problem is caused by the new DataSample($m) statement in the consequence of the init
rule that causes an initialization of the DataSample type declaration without registering
it on the PackageRegistry
