“range=-n” support may add

> for last n bytes

if (StringUtils.isEmpty(bounds[0])) {//
				nums = Long.valueOf(bounds[1]);
				from = (size > nums) ? size - nums : 0;
				to = size - 1;
			} else {

> check for range byets could be added too, if the arg is wrong, the range list should be empty but no parse exception.

Thank you for reporting this! I'll consider to add this in the next release (but there is not ETA for it yet).
