Is HCL Notes/Domino using Oracle Java?- 13 October 2023 - (0) Comments
Thomas Hampel
13 October 2023The short answer: No!
Background:
On January 23, 2023, Oracle announced (again) yet another new licensing model for Oracle Java that represents a dramatic price increase for large organizations.
This can lead to interesting discussions since e.g., a 40,000-employee organization could be asked spending USD $2.5M annually just on Oracle Java alone.
What Java version is used by Notes and Domino?
Notes and Domino are providing the Java runtime as part of the product, so customers do NOT need to download or install the Java runtime environment separately.
Since the JVM/JDK is part of the licensed product, it is covered under the product license of HCL or previously the product license of IBM.
With the acquisition of the product by HCL, dependencies to IBM Java were removed and got replaced with OpenJDK effectively in version 11.0.0 of HCL Notes/Domino.
Java updates are provided by HCL (and previously by IBM) typically as part of regular fix packs.
Here is a simplified overview of what Java version is used in the product:
Notes/Domino | Java Version | Java Vendor | JVM | Remarks |
14.0.x | 17 LTS | IBM Semeru | OpenJ9 | Open Edition |
12.0.x | 8 | AdoptOpenJDK, later IBM Semeru | OpenJ9 | renamed to Adoptium |
11.0.x | 8 | AdoptOpenJDK, later IBM Semeru | OpenJ9 | renamed to Adoptium |
10.0.x | 8 | IBM | IBM J9 | see IBM FAQ |
9.0.1 | 8 | IBM | IBM J9 | see IBM FAQ |
9.0.0 | 6 | IBM | IBM J9 |
a more comprehensive overview of which Java flavour and patchlevel is included in which release of Domino is provided later on in this blog post.

Special cases and exceptions?
- MacOS : old versions of the IBM Notes Client before(!) 9.0.1 IF17 did not include any Java runtime. Customers may have manually installed a JVM, e.g. the Oracle runtime.
Starting with Notes Client 9.0.1 IF17 the product includes the IBM Java runtime. Customers are encouraged to upgrade to a more current version of the HCL Notes Client for MacOS. - IBMi (=iSeries) : HCL Domino will use the version provided by the platform.
- HCL Client for Application Access (HCAA), formerly known as IBM Client for Application Access (ICAA), does not provide a Java VM, it uses a JVM that you choose to install yourself.
Only for acessing Domino applications that are running Java code >in< the HCAA client, a JVM needs to be provided.
What about Nomad, Verse, Enterprise Integrator, SAP Connector, etc?
These products are addons to Domino and unless otherwise specified they leverage the JVM provided by Domino.
IBM? OpenJDK? Semeru? Adoptium? Eclipse? - Are you confused as well?
It's not easy to even get a basic understanding of the various project names, forks, branches and takeovers, but I'll try providing a short intro without covering the entire history of Java nor what Java itself is.
In the context of Notes and Domino, this is what you need to know:
- OpenJDK is a free and open-source implementation of the Java Platform, Standard Edition (Java SE), it is a Java Development Kit (JDK)
- OpenJ9 is a java virtual machine (JVM), contributed to the Eclipse project by IBM
- AdoptOpenJDK was a project for producing vendor neutral builds of OpenJDK
- AdoptOpenJDK merged into Eclipse Adoptium, to provide a prebuilt OpenJDK, that release is now named Temurin
With this move, Adoptium is, according to them, is not allowed to release OpenJ9-based or GraalVM-based runtimes - IBM comes to the rescue and provides OpenJ9 builds at no charge as the IBM Semeru runtime which includes the OpenJ9 Java VM
- IBM Semeru comes in two flavours:
a) IBM Semeru Runtime Open Edition, which is open source (GPLv2) licensed and is not TCK (Technology Compatibility Kit) certified
b) IBM Semeru Runtime Certified Edition, which is Java TCK-certified - Former "IBM Java" has been moved into IBM Semeru Runtime Certified Edition at Java version 11
- HCL Notes and Domino are using IBM Semeru Open Edition.
For better understanding of the above, here is a chart that explains:
As outlined above, HCL Notes and Domino is embedding IBM Semeru and does not use any Oracle Java.

How to check which Java version is used?
From the program directory of the Notes client or Domino server:
cd jvm/bin
./java -version
Example:
Checking the Java version used by the HCL Notes Client 14.0 (Early Access version) on Windows:
C:\Program Files\HCL\Notes>cd jvm/bin
C:\Program Files\HCL\Notes\jvm\bin>java -version

Finally:
I hope this brief explanation will help to better understand the usage of Java in our product and provides you with enough of a justification to upgrade to the most current version of HCL Notes and Domino.
so upgrade NOW !
