Description

I have created a sample project with a simple JUnit test here:

https://github.com/JWT007/log4j2_logLevelClass

Basically I have an inner class and when I get a logger for that class I get the logger named.

Log4jLevelTest.InnerClass

and I can see its associated LoggerConfig of the same name.

If I call "Configurator.setLevel(InnerClass.class, Level.DEBUG)" it does not change the level of my logger but rather creates a new LoggerConfig with the following name:

Log4jLevelTest$InnerClass

Here the output of my sample test:

 

 ==================================================================================
Class name                :: Log4jLevelTest$InnerClass
 ==================================================================================
Logger name               :: Log4jLevelTest.InnerClass
Logger level              :: INFO
Configured Loggers (1)    :: 
  o Log4jLevelTest.InnerClass(INFO)
 ==================================================================================
>> Configurator.setLevel(Inner.class, Level.DEBUG)
Logger name               :: Log4jLevelTest.InnerClass
Logger level              :: INFO
Configured Loggers (1)    :: 
  o Log4jLevelTest.InnerClass(INFO)
  o Log4jLevelTest$InnerClass(DEBUG)
