You could make Outer.super.m() a deprecated syntax for calling super on an outer instance (emit a warning) and offer alternative Outer.this.super.m() as a replacement.

In a distant future (JDK10 or 11), the deprecated syntax would then be removed and Type.super.m() used exclusively for calling super interface methods...
