[?(@ empty false)] Filter is not working after json-path 2.4.0 release

[rosensilva]

Hello,

We noticed that the ?(@ empty false) expression is not working with the latest json-path version. I have tried this with a simple java program with versions 2.4.0 to 2.7.0. Seems like this is broken from 2.5.0 upwards.

Below is the sample java program,

package org.example;

import com.jayway.jsonpath.JsonPath;

public class Main {
    public static void main(String[] args) {
        String scenarioStateJson ="{\n" +
                "  \"data1\": {\n" +
                "    \"data\": [\n" +
                "      {\n" +
                "        \"attribute1\": \"string1\",\n" +
                "        \"attribute2\": \"string2\"\n" +
                "      },\n" +
                "      {\n" +
                "        \"attribute1\": \"string3\",\n" +
                "        \"attribute2\": \"string4\"\n" +
                "      }\n" +
                "    ]\n" +
                "  },\n" +
                "  \"data2\": {\n" +
                "    \"data\": [\n" +
                "      {}\n" +
                "    ]\n" +
                "  },\n" +
                "  \"data3\": {\n" +
                "    \"data\": [\n" +
                "      {\n" +
                "        \"attribute1\": \"string5\",\n" +
                "        \"attribute2\": \"string6\"\n" +
                "      },\n" +
                "      {\n" +
                "        \"attribute1\": \"string7\",\n" +
                "        \"attribute2\": \"string8\"\n" +
                "      }\n" +
                "    ]\n" +
                "  }\n" +
                "}";
        JsonPath jsonPath = JsonPath.compile("$..data.*[?(@ empty false)]");
        Object jsonPathValue = jsonPath.read(scenarioStateJson);
    }
}

The following exception is thrown,
