Yes. @Contended on class is currently the shorthand for the @Contended
with the same (but unknown) tag over all the fields. However, in future
this might change, because @Contended on class might also guard the
object header, as soon as we are brave enough to tap into the GC
interface to allocate the @C objects aligned for the cache line boundary.
