Description

Hi, I am trying to migrate one of the app from 1.x to 2.15.0. We were using MDC for lookups and as per bridge api, we can still use MDC for lookups.

In Code, we use

 

MDC.put("PID", someFunction());

 

FYI, MDC.get("PID) gives correct lookup information

Configuration File-

 

appender.rolling.layout.type = PatternLayout
appender.rolling.layout.pattern = %d{dd MMM yyyy HH:mm:ss,SSS} %-5p [%t] [%X{PID}] %c - %m%n

But, %X{PID} is giving blank. 

 

Dependencies we are using-

1. log4j-1.2-api-2.15.0.jar
2. log4j-api-2.15.0.jar
3. log4j-core-2.15.0.jar
4. log4j-jcl-2.15.0.jar
5. commons-logging-1.1.1.jar
