如何解决 org.apache.commons.compress.archivers.zip.UnsupportedZipFeatureException

已解决 zip commons-compress

当解压缩 zip 文件时，我的 jboss 显示错误。

错误消息：

14:36:20,663 ERROR [STDERR] org.apache.commons.compress.archivers.zip.UnsupportedZipFeatureException: unsupported feature data descriptor used in entry mimetype
14:36:20,663 ERROR [STDERR]     at org.apache.commons.compress.archivers.zip.ZipArchiveInputStream.read(ZipArchiveInputStream.java:245)
14:36:20,663 ERROR [STDERR]     at java.io.InputStream.read(Unknown Source)

这里的 test.epub 压缩文件内部文件详情：

使用的是 commons-compress-1.4.jar， 1.5 版本也同样显示这个错误。

有人知道为什么发生错误，我如何解决？

这是源代码：

public void unzip(InputStream is, File destDir, String charsetName)
        throws IOException {
    ZipArchiveInputStream zis;
    ZipArchiveEntry entry;
    String name;
    File target;
    int nWritten = 0;
    BufferedOutputStream bos;
    byte[] buf = new byte[1024 * 8];
    zis = new ZipArchiveInputStream(is, charsetName, false);
    while ((entry = zis.getNextZipEntry()) != null) {
        name = entry.getName();
        target = new File(destDir, name);
        if (entry.isDirectory()) {
            target.mkdirs();
        } else {
            Util.createParentDirectory(target);
            target.createNewFile();
            bos = new BufferedOutputStream(new FileOutputStream(target));
            while ((nWritten = zis.read(buf)) >= 0) {
                bos.write(buf, 0, nWritten);
            }
            bos.close();
            debug("file : " + name);
        }
    }
    zis.close();
}

当我使用其他 LIB（java.util.zip），还示出了下面的异常。

java.util.zip.ZipException: only DEFLATED entries can have EXT descriptor
    at java.util.zip.ZipInputStream.readLOC(Unknown Source)
    at java.util.zip.ZipInputStream.getNextEntry(Unknown Source)
