---------------------------------------
Summary: camel-jsonpath: Consider removing json-smart exclusion
Key: CAMEL-19714
URL: https://issues.apache.org/jira/browse/CAMEL-19714
Project: Camel
Issue Type: Improvement
Components: camel-jsonpath
Reporter: James Netherton
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[?([email protected]_id)]
{code}
You get:
{code:java}
