//测试数据
String test = """
{
"1": {
"a1": [{"id":"a1"},{"id":"a2"}],
"b1": [{"id":"b1"},{"id":"b2"}]
},
"2": {
"a2": [{"id":"a1", "id1":"a11", "userId": "a12"},{"id":"a2"}],
"b2": [{"id":"b1"},{"id":"b2"}]
}
}
""";
String jsonPath = "$.*.*.*";
System.out.println("com.alibaba.fastjson2: " + JSONPath.eval(test, jsonPath));
//测试结果：[[{"id":"a1"},{"id":"a2"}],[{"id":"b1"},{"id":"b2"}],[{"id":"a1","id1":"a11","userId":"a12"},{"id":"a2"}],[{"id":"b1"},{"id":"b2"}]]
//期望结果：[{"id":"a1"},{"id":"a2"},{"id":"b1"},{"id":"b2"},{"id":"a1","id1":"a11","userId":"a12"},{"id":"a2"},{"id":"b1"},{"id":"b2"}]

Start by running the supplied Java example with JSONPath.eval and inspect the JSONPath wildcard traversal behavior. Confirm whether $.*.*.* should flatten the nested arrays, then add a regression test for the expected list of objects and verify the result.
