You are probably correct. Have rebased a couple times before now but will
figure out why this is here.

> Project: Apache NiFi
> Issue Type: Bug

> When {{${attribute:replaceAll('\w+', 'replacement')}}} is called, the pattern
> is matched and applied. However, when {{${attribute:replace('\w+',
> 'replacement')}}} is called, it is not. I believe this is because
> {{ReplaceAllEvaluator}} uses {{String#replaceAll(String regex, String
> replacement)}} while {{ReplaceEvaluator}} uses {{String#replace(CharSequence
> target, CharSequence replacement)}} which then uses
> {{Pattern.compile(target.toString(), Pattern.LITERAL)}} instead of compiling
> for a regular expression. I am writing a unit test to demonstrate this and
> show the results when {{String#replaceFirst()}} is used instead.
