ElMehdi TAHRI updated LOG4J2-1153:
----------------------------------
Description:
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

In order to make this configuration work, i had to add the {{loggers}}
component and fill the identifiers. My question is why in xml file we can
define only a root logger and it works fine, and in a properties file it does
not work ?
