POIFSFileSystem java.io.IOException: Read error

使用POI解析word文档遇到java.io.IOException: Read error问题

jar包 poi-3.8.jar

private HWPFDocument getDocument() {
    if(this.document == null) {
        try {
            this.document = new HWPFDocument(this.inputStream);
        } catch (Exception var2) {
            logger.error("open failed!", var2);
            throw new WordParserException("1");
        }
    }

    return this.document;
}

HWPFDocument.class

public HWPFDocument(InputStream istream) throws IOException {
    this(verifyAndBuildPOIFS(istream));
}

HWPFDocumentCore.class

public static POIFSFileSystem verifyAndBuildPOIFS(InputStream istream) throws IOException {
    PushbackInputStream pis = new PushbackInputStream(istream, 6);
    byte[] first6 = new byte[6];
    pis.read(first6);
    if(first6[0] == 123 && first6[1] == 92 && first6[2] == 114 && first6[3] == 116 && first6[4] == 102) {
        throw new IllegalArgumentException("The document is really a RTF file");
    } else {
        pis.unread(first6);
        return new POIFSFileSystem(pis);
    }
}
