[jira] [Updated] (LOG4J2-1572) Empty NDC stack logs null
[ https://issues.apache.org/jira/browse/LOG4J2-1572?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Johno Crawford updated LOG4J2-1572:
-----------------------------------
Description:
Expected behavior
When the NDC stack is empty nothing should be logged (regression in log4j 2.x, the functionality behaves this way in log4j 1.2).
ex. 2016-09-09 09:54:44,212 INFO [main] Main (Main.java:6) - huuhaa
Actual behavior
When the NDC stack is empty null is logged.
ex. 2016-09-09 09:54:44,212 INFO [main] Main (Main.java:6) - huuhaa null
{code:java}
import org.apache.logging.log4j.LogManager;
public class Main {
public static void main(String[] args) {
LogManager.getLogger(Main.class).info("huuhaa");
}
}
{code}
{code:xml}
<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
<Appenders>
<Console name="STDOUT" target="SYSTEM_OUT">
