[logback-user] NoSuchMethodException in sysoutslf4j.PrintStreamCoordinatorFactory

When calling SysOutOverSLF4J.sendSystemOutAndErrToSLF4J(), it always complains about NoSuchMethodException for sun.misc.Launcher$AppClassLoader.addURL(java.net.URL) I wonder if it should be addAppURL(...) instead of addURL(...)?
