Major Compiling a rule like (*1) which is described in MVEL dialect and uses one of the four basic binary operators ('+', '-', '*', '/') taking BigDecimal type value(s) as operand(s) with executable rule models enabled, a compilation error like (*2) occurs.
(*1)
package com.example.reproducer
import com.example.reproducer.Bus
import java.math.BigDecimal
dialect "mvel"
rule "bus3b"
when
$bus : Bus()
then
// Actually, errors can occur at all the four basic operators '+', '-', '*', '/' taking BigDecimal as an operand/operands.
BigDecimal grossWeight = $bus.weight + $bus.capacity * 55 + $bus.maxLoadingWeight;
System.out.println("***** " + $bus + ", gross weight = " + grossWeight);
end
$bus.weight and $bus.maxLoadingWeight are BigDecimal type properties.
