/**
|
|
* This exhibits a regression case, that albeit weird, is valid according to the JSR 330 spec. JSR
|
|
* 330 specifies a rough ordering by which members should be injected, and it is possible to rely on
|
|
* such ordering. When members injecting {@link Subtype}, field injection is guaranteed to be
|
|
* performed on {@link Base} first. The binding for {@code @FirstToString} in {@link
|
|
* OrderingModule#provideToString()} relies on this ordering, and thus uses the value in {@link
|
|
* Base#first} to satisfy the binding.
