@magnolia-k It seems that strictOptionParsing, which we use, makes a difference here, if you use `implicit val formats: Formats = new DefaultFormats { override val strictOptionParsing = true }` Then...

Ok, I understand that this is the reason why the exception happens, but It does not explain why `JNothing.extractOpt[String]` should behave differently than `JNothing.extract[Option[String]]` when strictOptionParsing is true
