java使用ICE Tar库对大文件进行Tar

Question

我正在使用ICE焦油库制作焦油文件

我的代码片段是

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;

import com.ice.tar.TarEntry;
import com.ice.tar.TarOutputStream;


public class Util {
public static void main(String[] args) {
    tar();
}   
    public static void tar(){
        try{
      // Output file stream   
    FileOutputStream dest = new FileOutputStream( "f:/test/test.tar" );   
    // Create a TarOutputStream   
    TarOutputStream out = new TarOutputStream( new BufferedOutputStream( dest ) );   
    // Files to tar   
    File[] filesToTar=new File[2];   filesToTar[0]=new File("f:/test/myfile1.txt");   
    filesToTar[1]=new File("f:/test/myfile2.txt");  
    for(File f:filesToTar){      
        out.putNextEntry(new TarEntry(f));     
        BufferedInputStream origin = new BufferedInputStream(new FileInputStream( f ));     
        int count;     
        byte data[] = new byte[2048];     
        while((count = origin.read(data)) != -1) {        
            out.write(data, 0, count);     
            }     
        out.flush();      
        origin.close();  
        }  
    out.close();
        }catch(Exception e){
            e.printStackTrace();
        }
    }
}

然而，这只适用于小文件。当我尝试对大文件进行tar时，会出现以下错误：

java.io.IOException: request to write '2048' bytes exceeds size in header of '1495040' bytes
    at com.ice.tar.TarOutputStream.write(Unknown Source)

当我试图改变

byte data[] = new byte[2048];到byte data[] = new byte[origin.available()];

我有

java.io.IOException: request to write '1495040' bytes exceeds size in header of '1495040' bytes
    at com.ice.tar.TarOutputStream.write(Unknown Source)

我不知道为什么会这样。请帮忙

编辑： 我尝试tar的大文件本身就是tar文件
