    Description

      When arithmetic operations is used with a field(s) of BigDecimal in LHS like the following, 

      rule "rule_addition_bd"
    when
        $fact : Fact( $bd: (bd1 + bd2) )
    then
        System.out.println("***** $fact: " + $fact + ", bd1 + bd2 = "+$bd);
end

rule "rule_addition_int" 
    when 
        $fact : Fact( $bd: (bd1 + 100) ) 
    then 
        System.out.println("***** $fact: " + $fact + ", bd1 + 100 = "+$bd);
 end

      build of executable model fails with the error like:

      [ERROR] /path/to/reproducer_bd_arthmetic/target/generated-sources/drools-model-compiler/main/java/com/example/reproducer/P37/LambdaExtractor376B932463BA628A4DCB2BE232AC4A7B.java:[22,31] bad operand types for binary operator '+'
