exit code 2 with OKAY status (v2021.12.20)

Hi,

with the new update to v2021.12.20 i received a exit code 2 with a  OKAY jar, why?
```
-- github.com/mergebase/log4j-detector v2021.12.20 (by mergebase.com) analyzing paths (could take a while).
-- Note: specify the '--verbose' flag to have every file examined printed to STDERR.
/opt/unifi-6.5.55-1d0581c00d/lib/log4j-core-2.16.0.jar contains Log4J-2.x   == 2.16.0 _OKAY_
