}

The code above reports that e should be replaced by an unnamed pattern while it’s used in the next line. JDK25 is in use.

Additional observations:

  1. SonarQube for Eclipse doesn’t show this issue (just SonarQube Cloud)

  2. If we remove Lombok @Getterand replaced it by plain getter Config.getIntervalMs the FP disappears

Thank you for the report! I’ve filed SONARJAVA-6455 to track resolution of this issue.
