spring boot drools ConstraintEvaluationException with multiple drl files - spring-boot

Question

I have one d.drl file under the src/main/resources/rule, it looks like:
package com.my.rest.service;
//set import and global
rule "groupA_A_0"
agenda-group "groupA"
activation-group "groupA_A"
when
$j : JSONObject(aSize == 1)
then
System.out.println("####A-0");
....
end
the code to fire is:
#Autowired
private KieContainer kieContainer;
public testA() {
KieSession kSession = kieContainer.newKieSession();
//...set global
JSONObject json = new JSONObject();
json.put("aSize", 1);
kSession.getAgenda().getAgendaGroup("groupA").setFocus();
kSession.insert(json);
kSession.fireAllRules();
}
it works fine.
However, if I add another a.drl whose is
package com.my.rest.service;
//set import and global
rule "groupB_A_0"
agenda-group "groupB"
activation-group "groupB_A"
when
$j : JSONObject(bSize == 1)
then
System.out.println("####A-0");
....
end
the corresponding code to fire is:
public testB() {
KieSession kSession = kieContainer.newKieSession();
//...set global
JSONObject json = new JSONObject();
json.put("bSize", 2);
kSession.getAgenda().getAgendaGroup("groupB").setFocus();
kSession.insert(json);
kSession.fireAllRules();
}
the error thrown when executing testB() which is used to fire rules of a.drl:
org.drools.mvel.ConstraintEvaluationException: Error evaluating constraint 'aSize == 1' in [Rule "groupA_A_0" in rule/d.drl]
JSONObject is net.sf.json.JSONObject(like a Map), aSize is put into JSONObject when fire rules of d.drl while bSize is put when fire rules of a.drl.
i just want to fire rules of a.drl, why it said the error of d.drl?(and at this time, fire rules of d.drl is successed)
how to fix it?
