    Description

      In executable model, build of the following pattern in LHS of a rule fails with error message (*1) for generated Java code (*2). While the same build succeeds in non-executable model.

      Fact( $ans : String.format("%,d", (value * new BigDecimal("1000")).longValue()) )    // "value" is a BigDecimal property of Fact class

      (*1) Error message

      [ERROR] Failed to execute goal org.kie:kie-maven-plugin:7.67.0.Final-redhat-00019:generateModel (default-generateModel) on project reproducer_bd_op_in_constraint_1a: Execution default-generateModel of goal org.kie:kie-maven-plugin:7.67.0.Final-redhat-00019:generateModel failed: [com/example/reproducer/P2A/LambdaExtractor2A3865EA6CC8B883951F6D08477ECCC6.java (21:795) : The operator * is undefined for the argument type(s) BigDecimal, long] -> [Help 1]

      (*2) Java code generated in executable model

      @Override()
public java.lang.String apply(com.example.reproducer.Fact _this) {
    return String.format("%,d", _this.getValue() * new BigDecimal("1000").longValue());
}

          Bug - A problem that impairs or prevents the functions of the product. DROOLS-7364 executable-model fails with BigDecimal arithmetic when it's a scope of a method call

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
