JDBC Driver compatible for Java 11 or 8

Hi Everyone.

My application (running on Java 11) is using the ReadyApi Virtual JDBC server for testing. I tried to use the jar file provided in the downloads ( and getting this error:

Caused by: java.lang.UnsupportedClassVersionError: com/smartbear/servicev/jdbc/driver/JdbcVirtDriver has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 55.0

Is there anyway I can download an older version of the Driver Jar that is compatible with Java 11/8?
