Not Ready to Upgrade From Java 8? Hit the Pause Button with Extended OpenJDK Support

Java

Java 8 has earned its longevity. It is stable, familiar, and deeply embedded in business-critical applications. Despite the fact that Java 25 is the latest release, staying on Java 8 has been a defensible decision for many organizations, not necessarily a sign that modernization has been ignored. 

But now support timelines from vendors who provide free OpenJDK downloads are forcing a new conversation. 

One important thing to call out: There is no universal OpenJDK 8 end of life date, since different distributions have different lifecycles. If you use Red Hat’s build of OpenJDK 8, however, one date matters: full support ends November 30, 2026. Staying on that build beyond the deadline requires a separate Extended Life Cycle Support (ELS) entitlement. 

That leaves teams not currently on RHEL (which includes Red Hat OpenJDK) with a decision: Should you upgrade Java 8, switch distributions and buy Red Hat ELS, or adopt open source, vendor-neutral OpenJDK 8 extended support? 

The short answer is that depends on more than the JDK. Watch this video that explores each option and keep reading to learn more.

Why Upgrading Java 8 Is Harder Than It Sounds

The long-term answer seems straightforward: upgrade to a current Java LTS release. Unfortunately, it's not just the runtime you have to take into account.

Production Java applications depend on technologies like Spring, Tomcat, Hibernate, Kafka clients, build tools, databases, monitoring agents, and security libraries. Changing the JDK can trigger framework upgrades, dependency changes, application testing, and infrastructure work. 

The javax to jakarta namespace transition is one example. To be precise, this change is not caused by moving off Java 8 itself. Jakarta EE 9 changed Jakarta EE APIs from the javax.* namespace to jakarta.*, creating implications across frameworks, application servers, libraries, build tools, and applications. 

For organizations moving from Spring Framework 5.3 or Spring Boot 2.7 to Spring Framework 6 or Spring Boot 3, the namespace transition can become part of a much broader modernization effort. Spring Framework 6 also requires JDK 17 as its minimum baseline. 

Even when an application compiles, a new JDK or framework version can introduce changes in production behavior and performance. That makes upgrading less like installing a new runtime and more like a platform migration requiring dependency analysis, regression testing, realistic load testing, and careful planning. 

So while upgrading should remain the long-term goal, the vendor’s deadline and your application’s readiness do not always line up.

What Are the Options for OpenJDK Extended Support? 

Organizations nearing a Java 8 support deadline generally have three practical choices:

  1. Upgrade now. If your applications, libraries, frameworks, and infrastructure are ready, moving to a current LTS release gives you a cleaner long-term position. 
  2. Stay with your current vendor through extended support. For Red Hat OpenJDK 8 users, purchasing ELS provides continuity on the existing distribution, though it requires an additional paid entitlement — and an operating system migration if you were not previously running your Java applications on RHEL. 
  3. Use another OpenJDK distribution or support provider. Free OpenJDK distributions may continue providing Java 8 updates, but receiving an updated build is different from having a commercial support relationship with contractual service levels and engineers available 24/7/365 when something fails. 

The important question is not simply, "Can I get a Java 8 build?" but rather "What happens when something goes wrong?"

Eclipse Temurin vs. Paid Java Support

The Eclipse Adoptium project publishes Java 8 binaries and offers community support. Organizations can submit issues and receive fixes through subsequent releases. But Adoptium also points organizations that require dedicated support and service-level agreements toward commercial providers like OpenLogic. 

So Eclipse Temurin vs. paid Java support is not really an apples-to-apples comparison. Temurin is a JDK distribution. Commercial support is an operational relationship. 

For organizations with deep in-house Java expertise, a free distribution may be perfectly reasonable. Other teams need someone who is contractually accountable when a production issue appears, particularly when it is unclear whether the root cause is Java at all. 

That leads to an important consideration for any extended support decision: How much of your actual Java environment does the provider support?

The Benefits of Support That Goes Beyond the Runtime

Java support discussions frequently become too narrow, as though applications run on a JDK in isolation. In reality, they run on a stack. 

Here's an example to illustrate why this matters: Imagine you deploy a patched OpenJDK build and subsequently see a performance problem in Tomcat. Is the issue JVM configuration? Tomcat threads? Memory allocation? A Spring dependency? Something in the application itself? 

A Java-only support provider (e.g., Azul) focused only on the runtime may be able to tell you that the JDK is functioning as expected. Technically, that may be true. Operationally, you still have a problem. 

OpenLogic’s approach to Java 8 support is broader. In addition to OpenJDK, OpenLogic can support technologies surrounding the runtime, including Spring Framework, Spring Boot, Apache Tomcat, and Apache Kafka — as well as the other OSS technologies to which they connect, such as MariaDB, Postgres, MongoDB, Redis, the underlying Linux operating system, and more. Instead of determining which vendor owns which layer before troubleshooting can begin, teams can work with one support partner across more of the open source stack. 

That is particularly valuable for older Java environments, where the JDK may be only one component approaching or already beyond its standard community support lifecycle.

A Path to OpenJDK 8 Support With Less Lock-In

OpenLogic OpenJDK Extended Support is intended for organizations that a few more years on Java 8 or Java 11. We provide open source OpenJDK builds and backports security fixes as needed. Tested and signed builds are delivered through a private repository, with documentation to fulfill patch management and audit evidence requirements. 

But the biggest advantage is flexibility for the future. 

Extended support should give you time to make the right technical decision, not simply move you into another ecosystem you will eventually have to work your way out of. When you are ready to modernize, OpenLogic can assist with assessment, migration planning, testing, and implementation of newer Java releases. Our extended support functions as a bridge to modernization rather than an indefinite destination from which you eventually need to navigate on your own.

There is also a practical difference in how the offering is structured. OpenLogic uses instance-based pricing rather than basing price on an organization’s total employee count, and customers continue using open source Java rather than adopting a proprietary JDK fork.

Should I Upgrade Java 8 or Buy Extended Support? 

For many organizations, this isn't an either/or decision. 

Upgrade Java 8 now if: 

  • Your applications and third-party dependencies support the target JDK. 
  • Your Spring, Tomcat, and other supporting technologies are ready to move. 
  • You have sufficient time for integration, performance, and regression testing. 
  • The migration can happen without introducing unnecessary operational risk. 

Consider extended support if: 

  • A vendor deadline arrives before your application is ready. 
  • Business-critical workloads cannot tolerate a rushed migration. 
  • Older frameworks or application servers complicate the upgrade. 
  • Vendor-controlled software blocks your move. 
  • The javax to jakarta transition requires significant remediation or testing. 
  • You need commercial accountability and a reliable source of security patches while you migrate. 

For a large Java estate, the sensible answer may be a hybrid strategy: upgrade the applications that are ready and put the rest under extended support while resolving dependencies and planning their OpenJDK migration. 

Extended support should not be an excuse to postpone modernization forever. Its value is that it separates two problems that do not necessarily need to be solved on exactly the same day: keeping an application secure and supported, and modernizing it responsibly.

Take Control of Your Java Roadmap

November 30 does not mean every Java 8 application suddenly needs to move to a new JDK. It means organizations using Red Hat’s OpenJDK 8 build need to decide what their supported path looks like after full support ends. 

Inventory your Java estate. Understand which frameworks, application servers, libraries, operating systems, and vendor applications are tied to each runtime. Then determine which applications are genuinely ready to upgrade and which need more runway. 

If you need that runway, extended support enables you to keep critical Java 8 workloads patched and supported while you modernize on a timeline driven by your applications rather than a vendor deadline.
