我最终确定,Logback正在管理自己的线程,即使在我的主要应用程序退出之后,它仍然保持活动.我搜索了一些解决方案,发现这是一种从Java内部明确关闭Logback的方法：

ILoggerFactory factory = LoggerFactory.getILoggerFactory();
if(factory instanceof LoggerContext) {
    LoggerContext ctx = (LoggerContext)factory;
    ctx.stop();
}

这真的是干净地关闭对数的唯一方法吗？我从来没有遇到一个日志记录系统(JUL,JCL,log4j等),使您明确关闭它,以便正常退出应用程序…

提前致谢！

更新：这里是logback.xml：

使用logback-1.0.13和JDK 1.6u34.
