You could implement your own wrapper around the ZipInputStream that ignores close() and hand that off to the third-party library.

thirdPartyLib.handleZipData(new CloseIgnoringInputStream(zipStream));


class CloseIgnoringInputStream extends InputStream
{
    private ZipInputStream stream;

    public CloseIgnoringInputStream(ZipInputStream inStream)
    {
        stream = inStream;
    }

    public int read() throws IOException {
        return stream.read();
    }

    public void close()
    {
        //ignore
    }

    public void reallyClose() throws IOException
    {
        stream.close();
    }
}
