FileUtils.copyDirectory因远程文件大于7兆而失败

进口：

import org.apache.commons.io.FileUtils;
import java.io.File;
import java.io.IOException;

代码：

String source = fm_dirIn;
File srcDir = new File(source);

// The destination directory to copy to. This directory
// doesn't exists and will be created during the copy
// directory process.
String destination = fm_dirOut;
File destDir = new File(destination);

try {
    // Copy source directory into destination directory
    // including its child directories and files. When
    // the destination directory is not exists it will
    // be created. This copy process also preserve the
    // date information of the file.
    FileUtils.copyDirectory(srcDir, destDir);
    return true
} catch (IOException e) {
    'Erreur : ' + e.printStackTrace();
}

结果

Erreur：null，并且复制的列表文件在此文件上停止为7040kb（31944 KB）
