Jayway's JsonPath returns empty array if key in the predicate is not present in JSON Data

[jimsha]

I am trying evaluate a JSON text using the expression $.sessions[?(@.key=='session3')].value using Jayway JsonPath 2.2.0 library.
JsonText = {
"username": xyz,
"empid": "1",
"sessions": [{
"key": "session1",
"value": "java"},
{
"key": "session2",
"value": "C"}]
}

It return empty object instead of null even if I am using Option.DEFAULT_PATH_LEAF_TO_NULL

I tried evaluating this through http://jsonpath.herokuapp.com/ and there also it returns empty array. Please help

An empty list is expected, see https://github.com/json-path/JsonPath#what-is-returned-when. DEFAULT_PATH_LEAF_TO_NULL would only have an effect if your sessions array contained an object that does not have the value property.
