Description Milos Gligoric CLA 2012-11-27 21:57:42 EST
Steps to reproduce:
1. Invoke "Extract Interface" on "ExtractInterfaceBug5", select all members, name interface "X", and "Use the extracted interface type where possible
2. The resulting code does not compile ("Type mismatch: cannot convert from X to ExtractInterfaceBug5")

public class ExtractInterfaceBug5 {
    void g(ExtractInterfaceBug5 o) {
    }

    public ExtractInterfaceBug5 f() {
        return null;
    }
}

class C5 {
    void f() {
        ExtractInterfaceBug5 c = new ExtractInterfaceBug5();
        ExtractInterfaceBug5 m = c.f();
        m.g(m);
    }
}

Issue is reproducible using I20121210-0800. The code refactoring results in compiler error.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug.

If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
