Drools 7.59.0 Migration to Drools 10.0.0

[dakshay4]

I am getting issue while migrating from Drools 7.59.0.Final to 10.0.0

I am Building KieBase using -

Kiebase kBase = new KieHelper().addContent(drlContent, ResourceType.DRL).build();

String drlContent is :

DRL package loan.management;
//generated from Decision Table
import loan.management.domain.model.fee.LendingChargeData;
// rule values at A9, header at A4
rule "Credit_Card_RTL_Full_Repayment_Done"
	when
		$charge:LendingChargeData($charge.getProductType() == ("Credit Card"))
	then
		$charge.setFeePercent(0);
end

This is the stack trace after calling

Drools 10.0.0 has been released. Any release notes available?

@dakshay4 github issue is used for tracking identified bugs. Please use zulip (https://kie.zulipchat.com/#narrow/channel/232677-drools) or mailing list (https://groups.google.com/g/drools-usage) for trouble-shooting.

Having that said, I think the issue can be resolved by

Kiebase kBase = new KieHelper().addContent(drlContent, ResourceType.DRL).build(ExecutableModelProject.class);
