OS DI 7.2.1 - UnsupportedClassVersionError

I am trying to get up and running with Data Integration 7.2.1 (on Windows 10).  As part of this, I am trying to import data via the SQL tBSInput node.  I installed the JTDS as required but I am now running into another Java error:

 

Exception in thread "main" java.lang.UnsupportedClassVersionError: com/microsoft/sqlserver/jdbc/SQLServerDriver has been compiled by a more recent version of the Java Runtime (class file version 57.0), this version of the Java Runtime only recognizes class file versions up to 52.0

I only have one version of Java installed, JRE 1.8.0_241.  I think I have the settings as they should be...but clearly I do not.  Any assistance would be much appreciated.

Hi
What is the JTDS driver version you are using? Have a try to use a more high version of JTDS driver.
