> json-smart is excluded in camel-jsonpath in favor of using Jackson.
> The problem is that json-smart is not truly an optional dependency. Depending on the jsonpath expressions used, you can end up with a ClassNotFoundException.
> E.g given this JSON:
> {code:java}
> {
>     "messages": [
>       {
>         "id": 1,
>         "text": "Hello, this is a message from a user."
>       },
>       {
>         "id": 2,
>         "text": "This is another message from a user."
>       },
>       {
>         "id": 3,
>         "text": "This message is from a bot.",
>         "bot_id": "123"
>       },
>     ]
>   }
> {code}
> And then using the expression:
> {code:java}
> $.messages[?(!@.bot_id)]
> {code}
> You get:
> {code:java}
> Caused by: java.lang.NoClassDefFoundError: net/minidev/json/writer/JsonReaderI
