George Adams: Eclipse Temurin can be used in a wide range of enterprise and cloud environments, and it provides several features that can help developers meet the demands of these environments. For example, Temurin can be used to build and run Java applications in a containerized environment, which can help with scaling and managing resources in a cloud environment. Additionally, Temurin provides long-term support for Java versions, which can reduce the risk of compatibility issues and help organizations plan for the future. Moreover, Temurin can be used to develop and deploy microservices-based applications, which are increasingly popular in cloud environments. Overall, Eclipse Temurin is a solid choice for developers and organizations looking for a reliable, scalable, and flexible Java runtime environment for enterprise and cloud applications.

Dreamix: Can you share the story behind choosing the name of Eclipse “Temurin”?

George Adams: The name “Temurin” was chosen as part of the Eclipse Adoptium project’s rebranding efforts in 2021. There are two reasons that the group chose the name: 1. Temurin is an anagram for the word Runtime and 2. The chemical composition of Temurin is nearly identical to the chemical composition of coffee. (This is what happens when you let engineers name projects!)

Dreamix: How does Adoptium handle security vulnerabilities, and what steps are taken to ensure that the distribution remains secure?

George Adams: Adoptium has a robust security policy that ensures the timely identification and mitigation of security vulnerabilities. Adoptium’s security policy includes proactive measures, such as code reviews, penetration testing, and continuous monitoring of the codebase. In the event of a security vulnerability, the project first determines if the vulnerability is in the OpenJDK source code or if it’s in Adoptium-specific code. If the vulnerability is in the OpenJDK source code the project will report the bug to the OpenJDK Vulnerability Group where several Java vendors will work on a fix. The Adoptium project has also recently started shipping SBOMs (software bill of materials) with Temurin allowing users to identify a full list of build dependencies and also in the near future allowing users to create a binary-identical reproducible build of Temurin on their own hardware.

Dreamix: How does Eclipse Temurin integrate with other tools and frameworks in the Java ecosystem, such as Maven or Spring?

George Adams: Eclipse Temurin integrates with a wide range of tools and frameworks in the Java ecosystem, including popular build tools like Maven, Gradle, and Ant. Developers can use these build tools to easily download and manage the Temurin runtime environment for their Java applications. Additionally, Temurin integrates seamlessly with popular Java frameworks like Spring, allowing developers to build robust and scalable enterprise applications.

Dreamix: How does Eclipse Temurin ensure compatibility with the latest versions of Java, and what strategies does it use to stay up to date with the evolving Java ecosystem?

George Adams: Eclipse Adoptium uses AQAvit, its comprehensive and adaptable quality assurance framework, to ensure compatibility with the latest versions of Java. AQAvit verifies that the Adoptium binary releases meet the highest quality standards by executing an extensive suite of tests, including functional, performance, stress, and system tests. It continually updates its testing matrix to align with the latest Java features and specification changes. By integrating AQAvit within its continuous integration and delivery (CI/CD) pipeline, Adoptium can automatically build, test, and validate each new release against the evolving Java ecosystem.

Dreamix: What are the potential drawbacks of Eclipse Temurin that developers/organizations should be aware of when choosing it?

George Adams: While Eclipse Temurin offers a high-quality, open-source distribution of OpenJDK, developers and organizations should be aware of potential drawbacks when considering its adoption. As a community-driven project, Temurin’s support and maintenance can be influenced by the community’s priorities and available resources, which may not always align with the specific needs of a developer or organization. Some organizations may wish to get commercial support for Temurin which several vendors including Red Hat, IBM, Azul and Microsoft can provide.

Dreamix: What do you see as the future of Java, and how is Adoptium positioned to play a role in shaping that future?

George Adams: The future of Java is likely to be marked by continued innovation, increased modularity, and a focus on performance improvements for modern applications, including cloud-native and microservices architectures. Adoptium, as an open-source project under the Eclipse Foundation, is well-positioned to play a significant role in shaping this future by providing high-quality, reliable, and up-to-date OpenJDK distributions. By fostering a collaborative community, Adoptium promotes knowledge exchange, shared resources, and active involvement in the Java ecosystem, which can directly impact the language’s evolution. Through its quality assurance efforts, including AQAvit, Adoptium ensures compatibility and adherence to standards, enabling developers to confidently adopt and contribute to Java’s growth.
