Database driver error while starting corda nodes - corda

Question

I have a bootstrapped corda network locally and distributed these artifacts to the respective VMs. While I start one of the node I am getting the below error: I am using azure sql as the backend and jars are compiled using corda enterprise 4.3 and the database driver used is jdbc 6.4.
IntelliJ project target is set to Java jdk 1.8 only.

Can you double-check you're using the jre8 version of the SQL Server JDBC driver.
