| subject | implementations of trait inherited methods shouldn't be 'protected' | |||
| code |
trait A {
protected def foo = "abc";
}
class B extends Object with A {
override protected def foo = "cde"
} |
|||
| what happened | If one calls A.foo on some instance of B it will get an IllegalAccessError. The reason is that trait A is transf\ ormed into an interface A, which is implemented by class B. Method 'foo' in the interface is public, but its imp\ lementation is 'protected', and generates a runtime exception. |
|||
| what expected | I see three options (listed in the order of my preference): - the mixin phase makes such methods public. - the backend continues to ignore protected modifiers. - the compiler rejects such code with an error. | |||
