> IOUtils#skipFully contains this code:
> {code}
>   public static void skipFully(InputStream in, long len) throws IOException {
>     while (len > 0) {
>       long ret = in.skip(len);
>       if (ret < 0) {
>         throw new IOException( "Premature EOF from inputStream");
>       }
>       len -= ret;
>     }
>   }
> {code}
> The Java documentation is silent about what exactly skip is supposed to do in 
> the event of EOF.  However, I looked at both InputStream#skip and 
> ByteArrayInputStream#skip, and they both simply return 0 on EOF (no 
> exception).  So it seems safe to assume that this is the standard Java way of 
> doing things in an InputStream.
> Currently IOUtils#skipFully will loop forever if you ask it to skip past EOF!
