All Implemented Interfaces:

com.jayway.jsonpath.spi.json.JsonProvider

public class FastJacksonJsonNodeJsonProvider
extends com.jayway.jsonpath.spi.json.JacksonJsonNodeJsonProvider

Custom json-path JsonProvider override to circumvent slow performance when encountering null paths as described in https://github.com/json-path/JsonPath/issues/396 Note that this only avoids errors for map properties, avoiding the exception on array paths is not possible without patching json-path itself
