Bug 129912 [clean up] no brackets only for 'return' and 'throws'
20060301 We should offer a third option where brackets in control stataments are only removed when the statement is a 'return' or 'throws'. This is a common code pattern for early exits or argument checking. if (type == null) throw new InvalidArgumentException("type must not be null");
