Make sure that: > > * You **don't** have [`log4j:log4j`](https://mvnrepository.com/artifact/log4j/log4j) on your classpath, I have checked its lib folder, POM, and IDE build path, no old Log4j 1.2 included. > * You have [`org.apache.logging:log4j-1.2-api`](https://mvnrepository.com/artifact/org.apache.logging.log4j/log4j-1.2-api) on your classpath, log4j-1.2-api-2.19.0.jar, log4j-api-2.19.0.jar, log4j-core-2.19.0.jar. just them. > * Either the system property `log4j1.compatibility=true` is set or `log4j.configuration` points to your `log4j.properties` file. doesn't have any system prop setting inside my program, but I do have a simple mechanism to read my properties file. ``` public class Log4j { public final static Logger LOG = Logger.getLogger(Log4j.class); private static boolean configurated = false; public Log4j() { }; public Log4j(String config_path) { if (configurated == false) { Properties p = new Properties(); try { p.load(new FileInputStream(config_path)); PropertyConfigurator.configure(p); configurated = true; } catch (IOException e) { System.out.println("[Error] Unable to read log4j config: " + e.getMessage()); } finally { if (p != null) { p.clear(); } } } }; } ``` This works fine since 1.12.x to 2.17.0 over the past few years. I still cannot understand why it won't on 2.19.0. -- This is an automated message from the Apache Git Service.
