@latency0ms -f arguement should be configuration file which contains file path list. It is not intended as scan target path itself. Use following command:
./log4j2-scan --trace --scan-log4j1 --scan-logback /opt/jedox/ps/

This works like a charm! Thanks!

@latency0ms Remove --silent option and add --trace --debug option, then you can see where scanner visits. If scanner visits infinitely, comment some errornous output.

I am getting this output using --trace --debug:
