自定义了一个Property类用于读取应用上下文下面的所有properties文件

Question

下面是定义的类，此类在windows下面运行很正常，但是在linux下面运行不正常，不知道是什么原因，有木有大神指教一下：
package com.cdsf.basicmanage.redirect.util;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.util.Properties;
import java.util.concurrent.ConcurrentHashMap;

public final class Property extends Properties {
private static final long serialVersionUID = 1L;
private static String baseURL = Property.class.getResource("/").getPath();

private final static class PropertyInstanceHandler {
    private final static Property properties = new Property();
}

private static final  String CLASS_PATH_NAME = "classes"; 

private static ConcurrentHashMap<String, String> concurrentHashMap = new ConcurrentHashMap<>();

private Property() {
    initIndex(baseURL.substring(1, baseURL.lastIndexOf(CLASS_PATH_NAME)));
}

public static Property getProperties() {
    return PropertyInstanceHandler.properties;
}

private void initIndex(String path) {
    File file = new File(path);
    if(!file.isFile()) {
        String[] files = file.list();
        for (String dir : files) {
            if(dir.equals(CLASS_PATH_NAME))
                continue;
            initIndex(path + File.separator + dir);
        }
    }else {
        String fullFileName = file.getName();
        if(fullFileName.contains(".")) {
            if(fullFileName.substring(fullFileName.lastIndexOf("."),fullFileName.length()).equals(".properties")) {
                    concurrentHashMap.put(fullFileName.substring(0,fullFileName.lastIndexOf(".")), file.getAbsolutePath());
                concurrentHashMap.keys();
            }
        }
    }
}

@Override
public String getProperty(String key,String filename) {
    try {
        if(!concurrentHashMap.containsKey(filename)) {
            return "";
        }
        load(new FileInputStream(new File(concurrentHashMap.get(filename))));
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return super.getProperty(key);
}

}

这个类在服务器会报如下的错误：
