InputStream is corrupted, skip() returns -1, causing the following loop be infinite.
> {code:java}
>   public final int skipBytes(int count) throws IOException {
>     int skipped = 0;
>     long skip;
>     while (skipped < count && (skip = in.skip(count - skipped)) != 0) {
>       skipped += skip;
>     }
>     if (skipped < 0) {
>       throw new EOFException();
>     }
>     return skipped;
