The question is why `Test$DC.setFoo(java.lang.Number)` is set as default setter, while the default call goes to `Test$AC.setFoo()`? Is this documented, or is there specification? I see that no tests exist for this, so it's not clear what is the expected behaviour. ------------- PR Comment: https://git.openjdk.org/jdk/pull/23443#issuecomment-2654710703
