I think it should throw SizeLimitException rather than faking the length because using wrong length may return broken value silently.
Changing count >= rawSizeLimit condition to count < 0 || count >= rawSizeLimit will work.

0xc4 is a bin8, which, according to spec stores a byte array whose length is upto (2^8)-1 bytes. Byte is signed, meaning that all values greater than 127 will be negative even when cast to int, so SizeLimitException in case of negative length is incorrect, that;s why I have introduced my change.

Oh, I see. You're right. I miss read the change.

I've merged. Thank you for the pull-req!

You are welcome!
