I'm trying to make common abstraction over

java.io.Writer

class. Given the

header abstract class Writer protected constructor()

in common module and

impl typealias Writer = java.io.Writer

in jvm module, it fails to compile with:

The following declaration is incompatible because some members are not implemented:
    public typealias Writer = Writer
No implementations are found for members listed below:

    protected constructor Writer()

    The following declaration is incompatible because visibility is different:
        protected/*protected and package*/ constructor Writer()
    The following declaration is incompatible because number of value parameters is different:
        protected/*protected and package*/ constructor Writer(p0: Any!)

Is it a bug or I'm missing something? Don't know how to make "protected/*protected and package*/ constructor"...
