Buggy source:

  if (JDBCConnectionFactory.isLoggable(Level.INFO_LEVEL)) {
    String logMsg="String_Node_Str";
    for (Enumeration enumeration=connProperties.propertyNames(); enumeration.hasMoreElements(); ) {
      String propName=(String)enumeration.nextElement();
      if (!propName.startsWith("String_Node_Str")) {
        logMsg+=(propName + "String_Node_Str" + connProperties.getProperty(propName)+ "String_Node_Str");
      }
    }
    JDBCConnectionFactory.log(Level.INFO_LEVEL,logMsg);
  }
  close();
  String dataSource=connProperties.getProperty("String_Node_Str");
  if (dataSource != null) {
    JDBCConnectionFactory.log(Level.INFO_LEVEL,"String_Node_Str");
  }
 else {

Fixed version (ground truth):
public void open(Properties connProperties) throws OdaException {
  if (connProperties == null)   throw new IllegalArgumentException("String_Node_Str");
  if (JDBCConnectionFactory.isLoggable(Level.INFO_LEVEL)) {
    String logMsg="String_Node_Str";
    for (Enumeration enumeration=connProperties.propertyNames(); enumeration.hasMoreElements(); ) {
      String propName=(String)enumeration.nextElement();
      String lcPropName=propName.toLowerCase();
      String propVal;
      if (lcPropName.indexOf("String_Node_Str") >= 0 || lcPropName.indexOf("String_Node_Str") >= 0)       propVal="String_Node_Str";
 else       propVal=connProperties.getProperty(propName);
      logMsg+=propName + "String_Node_Str" + propVal+ "String_Node_Str";
    }
    JDBCConnectionFactory.log(Level.INFO_LEVEL,logMsg);
  }
  close();
  String dataSource=connProperties.getProperty("String_Node_Str");
  if (dataSource != null) {
    JDBCConnectionFactory.log(Level.INFO_LEVEL,"String_Node_Str");
    throw new UnsupportedOperationException("String_Node_Str");
  }
 else {
    String url=connProperties.getProperty("String_Node_Str");
    if (url == null || url.length() == 0) {
      throw new DriverException("String_Node_Str",DriverException.ERROR_MISSING_PROPERTIES);
    }
    connectByUrl(url,connProperties);
  }
}
