JsonNodeAdapter is not nullsafe

[zzl221000]

version main

public class TestNullJsonObject {
    @Json
    @Data
    @AllArgsConstructor(staticName = "of")
    @NoArgsConstructor
    public static class WrapJsonObject {
        private JsonObject json;
    }

    public static void main(String[] args) {
        var jsonb = Jsonb.builder().build();
        jsonb.type(WrapJsonObject.class).fromJson("{\"json\":null}");

    }
}

result:

Exception in thread "main" io.avaje.json.JsonDataException: Expecting '{' as object start, instead found 'u' at position: 10, following: `{"json":nu`, before: `ll}`

Can you change the test case to (A) not use lombok and (B) include the imports so that it's clear what types are being used.

Also note that if you have a failing test case, you are most welcome to create a PR with the failing test case if you like.

Thanks.
