> InputStream.skip is returning -1 during exception conditions which leads the following logic to infinite loop:
> {code:title=loop}
> protected void drain(InputStream dis, long bytesRead) throws IOException
> {
>     long toSkip = totalSize() - bytesRead;
>     toSkip = toSkip - dis.skip(toSkip);
>     while (toSkip > 0)
>         toSkip = toSkip - dis.skip(toSkip);
> }
> {code}
