Key: NIFI-5474
URL: https://issues.apache.org/jira/browse/NIFI-5474
Project: Apache NiFi
Issue Type: Bug
Affects Versions: 1.7.1, 1.7.0

To reproduce, add "${this will fail}" to the ReplaceTest unit test resource
"hello.txt" and run one of the tests (like testRegexWithExpressionLanguage).
You'll end up seeing an error message like this:
