[jira] [Created] (NIFI-7994) ReplaceText concurrency issue

Peter Turcsanyi created NIFI-7994:
-------------------------------------

             Summary: ReplaceText concurrency issue
                 Key: NIFI-7994
                 URL: https://issues.apache.org/jira/browse/NIFI-7994
             Project: Apache NiFi
          Issue Type: Bug
          Components: Extensions
            Reporter: Peter Turcsanyi
            Assignee: Peter Turcsanyi


ReplaceText, when scheduled to run with multiple Concurrent Tasks, can result in corrupted data due to the concurrent / unprotected usage of {{additionalAttrs}} map (storing the capturing groups with their current matches) in {{RegexReplace}} class (https://github.com/apache/nifi/blob/badcfe1ab7b7166decb92a0d427ba48fbf613400/nifi-nar-bundles/nifi-standard-bundle/nifi-standard-processors/src/main/java/org/apache/nifi/processors/standard/ReplaceText.java#L497).
