Fix the error prone error about flogger arguments

The following error gets fixed:
  error: [FloggerLogString] Arguments to log(String) must be compile-time constants or parameters annotated with @CompileTimeConstant. If possible, use Flogger's formatting log methods instead.
    log.atFine().withCause(e).log(e.getMessage());
                                  ^
