Jonathan Ellis commented on CASSANDRA-3231:
-------------------------------------------
looks like that's from the old hexToBytes implementation, where the inner loop
used to be
{code}
bytes[i] = (byte)Integer.parseInt(str.substring(i*2, i*2+2), 16);
{code}
So I think it's safe to remove now.

> As reported on irc, if you try to create an index on a CF with a default
> comparator of BytesType, but you supply invalid hex, weird things happen.
> Namely if you try to create one on 'category' you instead get one on
> '\xca\xfe\xff\xff', which is 4 bytes that appears to coincide with attempting
> to interpret 'ca', 'te', 'go', 'ry' as hex.
