At ReplaceText
<https://raw.githubusercontent.com/apache/nifi/master/nifi-nar-bundles/nifi-standard-bundle/nifi-standard-processors/src/main/java/org/apache/nifi/processors/standard/ReplaceText.java>processor
we have:

As you can see, only if *StackOverflowError *is raised during the
evaluation, the flowfile is send to failure relationship. I would like to
update the code to use Exception or NifiExpressionFailedException (if it
exits).
