Fix bug in Java OA constructor causing warning in finalizer

[externl]

Ensure _state is set to StateDestroyed otherwise we sometimes get a warning from the finalizer. Saw this warning when running tests in a slower container.

Looks good, but we should remove Java finalize which was deprecated in Java 9. For a future PR.

We shouldn't be doing this. Otherwise we'll never know if the formatting is bad.

then let's remove it.
