    Description

      When comparing BigDecimal type property with result of accumulate max of BigDecimal like the following,

              accumulate( Fact($bd: bd); $maxBd:max($bd))
              $fact : Fact( bd  == $maxBd)
      

      compilation in executable model fails with ERROR like the following.

      [ERROR] /path/to/reproducer_bd_accumulate_result_compare/target/generated-sources/drools-model-compiler/main/java/com/example/reproducer/Rulesfb93dfe4037d47349427eadc64c3e841RuleMethods0.java:[43,137] no suitable constructor found for BigDecimal(java.lang.Number)

      [ERROR]       (argument mismatch; java.lang.Number cannot be converted to long)
      [ERROR]
      

      This works with non-executable model.
