The swallowOutput option is a remedy for direct System.out.println() calls. One should not expect it to work with something that gets a direct reference to System.out stream before Tomcat replaces it. For example, it Tomcat is reconfigured to use Log4J for its own logging, and one configures a ConsoleAppender for Tomcat, this ConsoleAppender is not affected by swallowOutput. The limitations are documented here: http://tomcat.apache.org/tomcat-8.0-doc/logging.html#Console If you do not want to log to stdout/stderr, you really must not configure any ConsoleAppender,.
