Suppressing entire log statements from "stdout", "stderr" or specific log category in JBoss EAP 6.x, 7.x, or 8.x

Issue

• How to disable entire log statements from the stdout log category (System.out) and the stderr log category (System.err) in the JBoss EAP 6/7/8?
• How to suppress the stdout log messages from server.log, but still output it to console output.

• We are dealing with vendor java software that is logging too much like the following stdout and filling up disk space. We needs to suppress these lines.
