Description Justin McCartney 2016-07-12 09:05:16 UTC 
The Response JSON extractor logs a message at ERROR level if the specified JSON path expression cannot be found.

For example:

2016/07/12 09:44:16 ERROR - jmeter.extractor.json.jsonpath.JSONPostProcessor: Error processing JSON content in Response Json Extractor, message:No results for path: $['companyId']

I believe that this should not be even an INFO level message.  Consider the XPathExtractor which logs no message for a element that is missing or cannot be found.

As the JSONPostProcessor also sets the variable to a specific default value if it cannot be found I feel the log message should be moved to debug level logging.

This is causing our logs to be spammed with false "errors" when in fact the server has failed to respond under load and therefore the json element will not be present.
