 Review comment:
   thrown IOException should be logged. So can you include this exception where it is re thrown i.e. 
    `
   ...
   ...
   setConfiguration();
       }
       catch (IOException e) {
         throw new IllegalArgumentException("Could not configure Kerberos principal name mapping.", e);
       }`
