["Florian Bonte (Jira)" <ji...@apache.org>]

Florian Bonte created LOG4J2-3543:
-------------------------------------

             Summary: ContextData is not serialised through JsonLayout
                 Key: LOG4J2-3543
                 URL: https://issues.apache.org/jira/browse/LOG4J2-3543
             Project: Log4j 2
          Issue Type: Bug
    Affects Versions: 2.17.2
            Reporter: Florian Bonte


Values that are contained in the ContextData are included in the LogEvent, but when serialised through a JsonLayout, are not present in the resulting JSON string.

Example:

Screenshot of a debugger. When a log occurs, the LogEvent object has a reference to the contents of the ContextData.

 

Then after passing this LogEvent through the method toSerializable() in the class org.apache.logging.log4j.core.layout.AbstractJacksonLayout, the contextData is absent from the resulting JSON object:
 
{{{}}
{{  "instant" : {}}
{{    "epochSecond" : 1655893941,}}
{{    "nanoOfSecond" : 869382600}}
{{  },}}
{{  "thread" : "AWT-EventQueue-0",}}
{{  "level" : "INFO",}}
{{  "loggerName" : "(sensitive)",}}
{{  "message" : "(sensitive)",}}
{{  "endOfBatch" : false,}}
{{  "loggerFqcn" : "org.apache.log4j.Category",}}
{{  "threadId" : 25,}}
{{  "threadPriority" : 6}}
{{}}}

 

There does not appear to be a way to include the contextData in the JSON.
