log4j appenders force initialization of the appender/handler on reboot ---------------------------------------------------------------------- Key: WFLY-1379 URL: https://issues.jboss.org/browse/WFLY-1379 Project: WildFly Issue Type: Bug Components: Logging Affects Versions: 8.0.0.Alpha1 Reporter: James Perkins Assignee: James Perkins Fix For: 8.0.0.Alpha2 Adding a log4j appender works until the server is rebooted. The difference in the class names, {{org.apache.log4j.SomeAppender}} and manually added {{org.jboss.as.logging.logmanager.Log4jAppenderHandler}}, results in the handler being reconfigured. This also hits a bug (LOGMGR-58) in the logmanager where null references are can be retrieved before a full commit is invoked.
