Description

During upgrading log4j2 in grails 2.5.4 application, I removed all log4j 1.2.17 dependencies and added following dependencies pertaining to v2.17.1:

• log4j-api
• log4j-core
• log4j-1.2-api
• log4j-slf4j-impl

 

Here's my log4j2.properties file present under conf directory:

rootLogger.level = INFO
rootLogger.additivity = false
rootLogger.appenderRefs = stdout
rootLogger.appenderRef.stdout.ref = STDOUT

appender.console.type = Console
appender.console.name = STDOUT
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = %m%n
 

 

I noticed that internal framework logs were also appearing and on further debugging I found that the additivity property for root logger was set to true (even when it is set to false in properties file). 

 

I've posted a question with further details on stackoverflow.
