Interop: Java setter not seen by ceylon code when it overrides a setter in a java interface

[@jpragey] This one bites when I tried to use jface preferences from ceylon (hence the names). Java code:

public interface MyInterface {
}

public interface MyIPreferencePage {
    public void setContainer(MyInterface preferencePageContainer);
}

public class MyPreferencePage implements MyIPreferencePage {

    private MyInterface intf = null;

    public MyInterface getContainer() {
        return intf;
    }

    public void setContainer(MyInterface container) {
        this.intf = container;
    }
}

called by ceylon code:

shared class MyPrefPage() extends MyPreferencePage() {}

Leads to

[ceylon-compile] /home/jpragey/workspace4/MyApp/build/src/org/myapp/run.ceylon:3: error: formal member setContainer of MyIPreferencePage not implemented in class hierarchy
[ceylon-compile] shared class MyPrefPage() extends MyPreferencePage() {
[ceylon-compile]              ^
[ceylon-compile] 1 error

It’s now 2017 and I’m also having this problem 😃

You mean when I don’t refine it?
