Why did we need a extra step to get ```content``` from ```json```, then create ```content``` as you said in ticket?
```
String xpath = String.format("%s/content[path='%s']/content", this.xpath(), path);
new JsonPatch(this.storage).patch(
    xpath,
    Json.createObjectBuilder().add("content", json.getString("content")).build() <----- why di we do that?
);
```
