Jaroslav Kamenik commented on CASSANDRA-8755:
---------------------------------------------
Hi,
I have meant simple cases as
String zone_parts[] = zone.split("-");
String res = input.replaceAll(":", "\\\\:");
where regexp is normal string/even one char, so usage of regexp is overkill.
> Replace trivial uses of String.replace/replaceAll/split with StringUtils
> methods

> Priority: Trivial
> Labels: lhf

> There are places in the code where those regex based methods are used with
> plain, not regexp, strings, so StringUtils alternatives should be faster.
