If you haven't noticed the jTDS driver for MS SQL hasn't been updated in a while (almost 6 years). In the past jTDS type 4 driver had performance and stability benefits over Microsoft's JDBC driver (Download Microsoft JDBC Driver for SQL Server - SQL Server | Microsoft Docs ).
However it might be just the right time to stop using jTDS and use the Microsoft JDBC driver. Some of the reasons for changing the driver could be
- Supportabilty - Microsoft's JDBC driver supports latest Java LTS versions 8 & 13
- Security - jTDS does not support TLS1.2 which is current standard for secure connections
- Better compatibility with MS SQL features
What to change?
- Driver - com.microsoft.sqlserver.jdbc.SQLServerDriver
- URL - jdbc.url=jdbc:sqlserver://dbhost:1433;databaseName=databasename;
