Signals VitroVivo - Is it supported to use OpenJDK instead of Oracle Java when running Signals VitroVivo?

In order to use Signals VitroVivo you need to have Java installed as this is a system requirement for the TERR package 'parallel'.

Java Requirement
To use the parallel package, you must have set JAVA_HOME. You can check for JAVA_HOME by running the command Sys.getenv("JAVA_HOME") in the TIBCO Enterprise Runtime for R console.
Running library(parallel) loads the terrJava package if it is not already loaded.

This article confirms that it is supported to use OpenJDK as the Java version when running Signals VitroVivo as long as the JAVA_HOME environmental variable is correctly set.
