When comparing BigDecimal type property with String literal like the following.

        $fact : Fact( bd == "150")

compile in executable model fails with java.lang.NumberFormatException like the following.

Caused by: java.lang.NumberFormatException: Character " is neither a decimal digit number, decimal point, nor "e" notation exponential mark.
