将文件移动到linux上托管的tomcat服务器上的另一个目录时出现不可预知的行为

Question

我在服务器上有一个位置说/home/work/inbox，我已经配置了一个石英监视器，以便拾取放置在该位置的任何.xml文件，并为每个文件启动工作流，然后相应的文件在/ home / work / inbox / metadata等子目录下移动。测试时我将.xml和.pdf文件放在收件箱目录中，有时.xml和.pdf文件都被移动到元数据文件夹我在下面的代码中做错了什么？为什么它有时仅移动.xml并且有时会移动所有这些？

Class clazz extends JobDetail implements Job{

    private static final String EXT_XML = ".XML";
    public void execute(final JobExecutionContext context)

            // Assume the code below is returning /home/work
            LandingStrip landingStrip = LandingStripFactory.getLS();
            // the code below returns all the files under /home/work/inbox
            final File[] files = landingStrip.getAllRtSuperQuickInboxFiles();
            if (files != null)
                {
                    LOG.info("Found " + files.length + " keyed files");

// Get all files is in another class and the inbox string returns /home/work/inbox

        final File dir = new File(inbox);

        return dir.listFiles();
