我在一个服务里也遇到了这个问题

 java.lang.Thread.sleep(Native Method)
 org.apache.log4j.helpers.FileWatchdog.run(FileWatchdog.java:104)
六月 07, 2016 3:53:51 下午 org.apache.jasper.servlet.TldScanner scanJars
信息: At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.
六月 07, 2016 3:53:51 下午 org.apache.catalina.core.StandardContext reload
信息: Reloading Context with name [/diff] is completed

出错后服务自动重启了，我的原因是 在声明Logger的时候把后台服务中的Logger携程了

private static final Logger logger = Logger.getLogger(Client.class);

clsss写错了，Client.clsss在调用完就结束了，所以后台服务就出错了
