Description

The JSON result type generates excessive logs when used in debug mode, since it shows a log for each pattern defined in the result, and a log for the final result. For example:

DEBUG org.apache.struts2.json.JSONUtil - Adding include property expression: actionMessages.*
DEBUG org.apache.struts2.json.JSONUtil - Adding include property expression: actionResult
DEBUG org.apache.struts2.json.JSONUtil - Adding include property expression: data.*
DEBUG org.apache.struts2.json.JSONUtil - Adding include property expression: fieldErrors.*
DEBUG org.apache.struts2.json.JSONUtil - [JSON]{"actionMessages":[],"actionResult":"success","data":{},"fieldErrors":{}}

It would be better to change the level used in the method addPattern to trace, since in debug mode the final result is quite more useful than the "Adding include". I'm attaching a patch for this.
