java.util.logging 无法正常工作"bug or feature"

Question

为什么日志"1 MAIN INFO"不工作，当我禁用所有日志从核心库。level=OFF。但是对于我的包，我启用了所有日志记录。为什么它只工作后，我有第二个记录器是由字符串实例化?

LibClass = new LibClass();

package com.mycompany;
   public class Main {
      private final static Logger logger = Logger.getLogger(Main.class.getName()); 
      public static void main(String[] args) throws IOException {
          FileInputStream fis = new FileInputStream("log.prop")
          LogManager.getLogManager().readConfiguration(fis);
          logger.info("1 MAIN INFO");
          LibClass libClass = new LibClass();
          libClass.doWork();
          logger.info("3 MAIN INFO");
     }
}
package com.mycompany;
    public class LibClass {
    private final static Logger logger = Logger.getLogger(LibClass.class.getName()); 
    public void doWork() {
        System.out.println("doWork");
        logger.info("2 doWork INFO");
}}

handlers= java.util.logging.ConsoleHandler
.level = OFF
java.util.logging.ConsoleHandler.level = ALL
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter
com.mycompany.level = ALL 

输出

doWork
[Пт июл 01 22:37:29 EEST 2016] INFO: com.mycompany.LibClass doWork - 2 doWork INFO 
[Пт июл 01 22:37:29 EEST 2016] INFO: com.mycompany.Main main - 3 MAIN INFO

谢谢大家。谢谢Andreas的正确回答。

问题在这里:Logger. getlogger (Main.class.getName())在Logger加载配置之前加载类时执行LogManager.getLogManager(). readconfiguration (fis).

解决方案

package com.mycompany;
public class Main {
public static void main(String[] args) throws IOException {
        FileInputStream fis = new FileInputStream("log.prop");
        LogManager.getLogManager().readConfiguration(fis);
        MainClass mainClass = new MainClass();
    }
}
package com.mycompany;
public class MainClass {
    private final static Logger logger = Logger.getLogger(MainClass.class.getName()); 
    public MainClass() throws IOException {
        logger.info("1 MAIN INFO");
        LibClass libClass = new LibClass();
        libClass.doWork();
        URL url = new URL("http://google.ru");//I don't want see 
        url.openStream(); // fine, finest logs from this code
        logger.info("3 MAIN INFO");
    }
}
package com.mycompany;
    public class LibClass {
    private final static Logger logger = Logger.getLogger(LibClass.class.getName()); 
    public void doWork() {
        System.out.println("doWork");
        logger.info("2 doWork INFO");
    }
}
handlers= java.util.logging.ConsoleHandler
.level = OFF
java.util.logging.ConsoleHandler.level = ALL
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter
com.mycompany.level = ALL 

输出

[Сб июл 02 04:32:11 EEST 2016] INFO: com.mycompany.MainClass <init> - 1 MAIN INFO 
doWork
[Сб июл 02 04:32:11 EEST 2016] INFO: com.mycompany.LibClass doWork - 2 doWork INFO
