Why am I am not getting a runtime exception with message "no empty, please" when running following code:
code:

```kotlin
class Car(val name: String, col: String) {
    val fuel = 100
    var color = col
        set(value) {
            if (value.isBlank()) {
                throw RuntimeException("no empty, please")
            }
            field = value
        }
}

```

```kotlin
fun main() {
    var car = Car("Maruti", "")
    println("Your car ${car.name} is of ${car.color}")
}

```
