public static void main(String[] args) {
        try {
            ...
        } catch (Exception e) {
            log.error("Arg1 = {}. Exception: {}", "arg1Value", e);
        }
    }

I got false positive violation:

Missing arguments, expected 2 arguments but have 1

I ran it via gradle. I'll provide more information if you need.

Pay attention, that issue is valid for cases when I got some field from exception instance or cast it to another exception.

You can workaround this issue, if you do not put the Exception as last argument, e.g. just swapping arg1Value and e avoids this false positive.
