Using Custom handlers adds a Log4j consoleAppender

Solution Verified - Updated -

Issue

  • stdout log in JBoss EAP 6.0.1 environment is showing duplicate log entries.

  • When specifying a custom handler in the logging subsystem, a log4j ConsoleAppender is systematically added to the root logger which leads to duplicate logs when applications or third party libraries logs with log4j.
