can we set log4j property 'Log4jContextSelector' per webapps war

Hi,

In my application, I have 2 processes running and there are 3 webapps war files which get deployed in tomcat version 9.0.60. Out of these 3 war files, one war file is internal to my application while other 2 are coming as final artifacts from artifiactory.

My war uses a custom logger and custom ContextSelector, however other 2 wars from artifactory uses standard logger and standard ContextSelector.

I have defined below system property as a static block in custom logger, however for some unknown reason when my war gets deployed this log4j jars don't find this property and leads to ClassCastException "java.lang.ClassCastException: org.apache.logging.log4j.core.selector.ContextSelector cannot be cast to logger.log4j2.CustomLog4j2ContextSelector". To fix this I have placed 'log4j2.component.properties' file on log4j jars class path, but with this fix, following harmless error get logged for other 2 wars "java.lang.ClassCastException: Cannot cast logger.log4j2.CustomLog4j2ContextSelector to org.apache.logging.log4j.core.selector.ContextSelector".

I am looking for help to come up with a solution where, when my war gets deployed then custom logger context "logger.log4j2.CustomLog4j2ContextSelector" should be used while when other 2 wars get deployed then  "org.apache.logging.log4j.core.selector.ContextSelector" should be used. Please let me know if you have any idea on this.

static {
    System.setProperty("Log4jContextSelector", "logger.log4j2.CustomLog4j2ContextSelector");
}


Content of file 'log4j2.component.properties' ->
Log4jContextSelector=logger.log4j2.CustomLog4j2ContextSelector
