Corda Sample App Node Deployment Build Failure : JRE Compatibility Issue

Question

Is Corda Node Deployment not supported on JRE greater than 1.8 ? Quite surprised to know that Corda Nodes are not upward compatible with JRE versions higher than JRE 1.8. It is quite difficult to keep a specific JRE version for an Enterprise Application. I am getting the following error in Corda Sample App Deployment due to JRE incompatibility ?

Here it's mentioned that

Corda runs in a JVM. JVM implementations other than Oracle JDK 8 are not actively supported.

Also, there was already a similar question, check here.
