1. Instead of the printing the stack trace on the console, It can be logged. 


{code:title=DBOutputFormat.java|borderStyle=solid}
    
public void write(K key, V value) throws IOException {
      try {
        key.write(statement);
        statement.addBatch();
      } catch (SQLException e) {
        e.printStackTrace();
      }
    }
{code}


2. Missing resource information can be logged. 

{code:title=CounterGroup .java|borderStyle=solid}

protected CounterGroup(String name) {
    this.name = name;
    try {
      bundle = getResourceBundle(name);
    }
    catch (MissingResourceException neverMind) {
    }
    displayName = localize("CounterGroupName", name);
  }


  private String localize(String key, String defaultValue) {
    String result = defaultValue;
    if (bundle != null) {
      try {
        result = bundle.getString(key);
      }
      catch (MissingResourceException mre) {
      }
    }
    return result;
  }
{code}
