Azul Zulu OpenJDK 11 Vs Oracle JDK

[varaande]

Hi Team 

How to validate the whether we installed AEM with Azul Zulu OpenJDK 11 or Oracle JDK?

Is there any potential issues if we install the AEM using  Azul Zulu OpenJDK 11 instead of Oracle JDK (Most of the time we used Oracle JDK but Amazon E2 server already installed the Azul Zulu OpenJDK 11.

Hi @varaande ,

Use SSH to connect to your Amazon EC2 instance. Replace your-instance-ip with the actual IP address or DNS name of your EC2 instance, and use the appropriate SSH key file if required: 

ssh -i your-key.pem ec2-user@your-instance-ip

  Replace ec2-user with the appropriate username based on the AMI you are using.

Once you are connected to the EC2 instance, run the following command to check the installed JDK version:

java -version

Azul Zulu OpenJDK 11 falls under support category A, which means Adobe provides full support and maintenance for this configuration. This configuration is covered by Adobe's quality assurance process. Oracle Java™ 11 is supported until September 2026 at a minimum.

So better to go with the recommended JDK as per Adobe doc: https://experienceleague.adobe.com/docs/experience-manager-65/deploying/introduction/technical-requi...

@varaande You can simply use java --version to check, for eg:

Azul Zulu OpenJDK LTS versions are supported for on-premises AEM deployments starting with version 6.5 SP9. Support and distribution of the Azul Zulu JDK LTS versions must be licensed directly from Azul by Adobe customers.

Just that- Adobe will no longer provide support and distribution of the Azul Zulu
JDK LTS releases. Other than that there should not be any potential issues.
