We have recently got questions about our recommendations for what Java virtual machine to use together with HCL RTist (and IBM RSARTE). In this post we'll explain our plans moving forward.
The background is that for a long time we have recommended the Oracle Java virtual machine and this is what we have used for the majority of our internal testing. However, Oracle has recently changed their support licensing rules and this has made us change our plans. See https://www.oracle.com/technetwork/java/java-se-support-roadmap.html for the details of the change, but essentially the support going forward will no longer be free of charge.
As a result of the changes we have moved to OpenJDK as our recommended Java distribution and OpenJDK is what we now will use in the majority of our internal testing of RTist.
OpenJDK is an open source implementation of Java and has widespread industrial support. To learn more about OpenJDK and how to install and use it see the following links:
- https://openjdk.java.net/: The main OpenJDK page
- https://jdk.java.net/: Download page for different versions and platforms
- https://adoptopenjdk.net/releases.html : An alternative download page for OpenJDK with more information
Remember that RTist only supports 64 bit Java 8, so when downloading from any of the links above choose this version of the Java virtual machine.
Note that we made the move to Open JDK for our internal testing already in sprint 2019.11 so this is already live. Also note that if you want to check the details of our recommendations look in the system requirements documents that is available in every release of RTist.
