ZipFile.getComment() should also check EFS bit like getInputStream() and getZipEntry() do.
While the current implementaion does NOT check this.

================
 /**
     * Returns the zip file comment, or null if none.
     *
     * @return the comment string for the zip file, or null if none
     *
     * @throws IllegalStateException if the zip file has been closed
     *
     * Since 1.7

    public String getComment() {
        synchronized (this) {
            ensureOpen();
            byte[] bcomm = getCommentBytes(jzfile);
            if (bcomm == null)
                return null;
            return zc.toString(bcomm, bcomm.length);
