Preferably, these new classes should be 100% managed and have their implementation generated by Gradle at runtime.

It's acceptable for implementation classes to be written to fit into existing code, but new classes must not instantiate managed properties or implement getters manually.

This is preferred:

```groovy
public interface NewThing {
    Property<String> getSomeProperty()
}
```

      /*
       * It's theoretically possible for Reference.reachabilityFence to exist under older VMs but
       * not work. (Under Android in particular, we really should check the API Level instead of
       * probing for methods....) But it's hard to imagine how reachabilityFence in particular could
       * exist but throw, so we propagate anything that's thrown, presumably an unchecked Exception
       * or Error.
       */
