Log4j 1.x bridge not printing out logs properly in the log files

Question

I am migrating my existing log4j 1.x to log 4j 2.17.1 and tried to use the log4j-1.2-api-2.17.1.jar so that I don't have to migrate any of my code. But when I use this method the logs don't get properly appended to the log files and the other logs that I have that is the business or technical logs they don't get written at all.

For example in the technical log the last line is only up to this:

2022-01-12T17:13:45,635 29901880 [pool-21-thread-2] INFO  <[]> tech.com.test.BaseResponseHandler - Response Code: [200] Response ContentType: [Content-Type: application/json] 
2022-01-12T17:13:45,

Is there anything I am doing wrong out here?

The pom file:

<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-core</artifactId>
    <version>2.17.1</version>
</dependency>

            <dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-api</artifactId>
    <version>2.17.1</version>
</dependency>

     <dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-1.2-api</artifactId>
    <version>2.17.1</version>
 </dependency>
 
 <dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-jcl</artifactId>
    <version>2.17.1</version>
</dependency>

Please note that I am using a custom Logging mechanism and was loading the property file by PropertyConfigurator but now loading it via this way:

//the url is the path of the custom log4j prop files
System.setProperty("log4j.configuration", url.getPath());

Deployment of the application is done on weblogic 12g and written in Java.

what needs to be done as the functionality is not working as expected?
