When calling GsonBuilder.registerTypeAdapter with a JsonSerializer or JsonDeserializer, it is made null-safe (see TreeTypeAdapter), i.e. the (de-)serializer will not be consulted when a null value is handled.

It appears this is currently not documented.

It should be documented in registerTypeAdapter and it should refer to TypeAdapter as alternative which does allow handling null-values.
