Experiencing weird issue while making FTP connection using hxtt diver

Question

I am trying to access one file via FTP using hxtt driver, but I am able to make a connection. If I pass username and password in URL it is successful, but I get an exception if I pass username and password separately in properties file. Please see details below:

Jars I have tried with:

• Text_JDBC40.jar latest jar
• Text_JDBC41.jar latest jar
• Text_JDBC42.jar latest jar

Works fine:

Class.forName("com.hxtt.sql.text.TextDriver").newInstance();
String url = "jdbc:csv:/ftp://<username>:<password>@www.hxtt.net/testdemo/sample?_CSV_Separator=,";

String sql = "select * from Test"; 
Connection con = DriverManager.getConnection(url);

Throws an exception:

Class.forName("com.hxtt.sql.text.TextDriver").newInstance();
String url = "jdbc:csv:/ftp://www.hxtt.net/testdemo/sample?_CSV_Separator=,";
Properties prperties = new Properties();
prperties.put("user", "<username>");
prperties.put("password", "<password>");
String sql = "select * from Test"; 

Exception:
