Hi, I was wondering, is the null check on JsonString valid? Or can it be handled a little bit better? See here: https://github.com/apache/johnzon/blob/master/johnzon-core/src/main/java/org/apache/johnzon/core/JsonStringImpl.java#L30
I'd prefer to not have to add null checks in my code, and the fluent interface works well, so I was wondering if it made sense for Johnzon to do a null check, and if the input is null add it as null instead? John
