    Description

      executable-model fails with a rule like this:

          when
        $fact : Fact( intToString(value1 * (value2 - 1)) == "20" )

      where Fact.value1 and Fact.value2 are BigDecimal.

      [com/example/reproducer/PB4/LambdaPredicateB48355ACDCC9A5CBEE370F85B0101A1E.java (21:886) : The operator - is undefined for the argument type(s) BigDecimal, int]

      non-executable model runs successfully.
