ElMehdi TAHRI created LOG4J2-1153:
-------------------------------------
Summary: Unable to define only rootLogger in a properties file.
Key: LOG4J2-1153
URL: https://issues.apache.org/jira/browse/LOG4J2-1153
Project: Log4j 2
Issue Type: Bug
Components: Configurators
Environment: Linux Ubuntu 14.04; Java 1.8; Log4j-2.4
Reporter: ElMehdi TAHRI
I've changed the version of log4j2 from 2.3 to 2.4 in order to load the
configuration via properties file. So i have converted the xml file, that
defines only <Root> in <Loggers> element, into a properties file.
This is a preview of the xml file :
{code:xml}
<Loggers>
<Root level="info">
<AppenderRef ref="ConsoleAppender"/>
</Root>
</Loggers>
{code}
And this is a preview of the properties file :
{code}
rootLogger.level = info
rootLogger.appenderRefs = console
rootLogger.appenderRef.console.ref = ConsoleAppender
{code}
This configuration throw a null pointer exception :
{noformat}Exception in thread "main" java.lang.ExceptionInInitializerError
Caused by: java.lang.NullPointerException
