Finalizability should be documented

Objects created without running a constructor cannot be automatically finalized; see https://bugs.openjdk.java.net/browse/JDK-6590839. For ObjenesisStd's default strategy on OpenJDK, this isn't a concern, because it uses the munged Object constructor; but for other Objenesis strategies, including the defaults for other JVMs, it may be. It'd be nice if this was documented (and better yet if there was a way to check it at runtime). Is ReferenceQueue behavior also affected (which would mean users couldn't just implement their own finalizer either)?
