Child class overrides lambda in parent class

public abstract class ParentActivity extends AppCompatActivity {

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(getContentView());
        findViewById(R.id.button_parent).setOnClickListener(view -> Toast.makeText(this, "Parent onClick", Toast.LENGTH_LONG).show());
    }

    public abstract int getContentView();
}

public class MainActivity extends ParentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        findViewById(R.id.button_child).setOnClickListener(view -> Toast.makeText(this, "Child onClick", Toast.LENGTH_LONG).show());
    }

    @Override
    public int getContentView() {
        return R.layout.activity_main;
    }
}

Clicking on button_parent shows a Toast with “Child onClick”

I opened an issue in the retrolambda project: https://github.com/orfjackal/retrolambda/issues/109

I guess this one here may be closed.

I did some tests building the retrolambda project locally. It appears the bug appears in this commit: https://github.com/orfjackal/retrolambda/commit/bf932457e45817cdee07f34c8c2059db44848e03

I have not done any investigation to understand what part of that commit introduces the bug.
