Log4j 1.2 Bridge not printing exception stack traces

While trying to migrate to Log4j 2.x from Log4j 1.x using Bridge API approach, the following behavious was observed.

logger = Logger.getLogger(loggerName);

logger.log(Level.ERROR, msg, t);

The above code snippet was generating the logger message along with the exception stack trace in Log4j 1.x.

PropertiesFactory ERROR (FactoryDbBase.java:getOptionalAttributeValue:113) [main] | Invalid Attribute DB Exception Occured.
InvalidAttributeDbException: Parameter [abc] in DB is invalid.

    whereas the Log4j 1.2 Bridge API is printing only the message without the throwable object information/stack trace.
