You're Not Just Running Java 8. You're Running an Entire EOL Stack.

The Java 8 extended support conversation usually goes one of two ways. Either teams are actively trying to migrate off it and running into walls, or they know they should migrate but haven't started yet. Either way, the focus is almost always on the JDK itself—on Oracle's extended support costs, on OpenJDK alternatives, on what version to move to next.

That's the wrong place to look.

The real risk isn't Java 8. It's everything running on Java 8. The frameworks, the middleware, the application servers, the ORMs—the entire dependency stack that was built for and alongside Java 8, much of which has already aged out of official support. Teams that fixate on the JDK while ignoring the surrounding ecosystem are solving 10% of the problem while leaving 90% of the exposure intact.

This is the Java 8 stack problem. And it's affecting more enterprise applications than most engineering leaders realize.

‍

What "End of Life" Actually Means for Your Stack

When Oracle ended public updates for Java 8 in 2019, it didn't just mean the JDK stopped getting patches. It set off a cascade. Every framework and library that had been built and optimized for Java 8 was now running on borrowed time—some already EOL, some approaching it, some quietly slipping into unsupported status without much fanfare.

Here's the uncomfortable truth: a Java 8 application in production today is almost certainly not just a Java 8 problem. It's a Spring 5 problem, or a Tomcat 8.5 problem, or a Hibernate 5 problem, or all three at once.

When a framework hits end of life, it stops receiving security patches. CVEs get reported but don't get fixed. Compliance auditors start asking questions. And the longer you stay, the larger the gap between what your scanner says and what your actual exposure is—because newly discovered vulnerabilities affecting EOL versions may not even get CVE assignments for those versions, even if the exploit works.

Let's go through the stack.

‍

The Frameworks That Powered Java 8 Apps—and Where They Stand Today

Spring Framework 5.x

Spring Framework 5 was the backbone of Java 8 enterprise development for years. It hit end of life in August 2024. That means no more security patches, no more bug fixes, and no more compliance coverage from the Spring team.

Teams still running Spring 5 in production are now operating with an unpatched application framework—regardless of what version of Java they're on. And because Spring 5 and Java 8 co-evolved, a significant portion of the Spring 5 install base is still on Java 8 or Java 11.

HeroDevs' Never-Ending Support (NES) for Spring covers exactly this scenario: ongoing security patches and CVE remediation for Spring Framework versions that have aged out of official support, so teams have time to plan a real migration rather than a panicked one.

Apache Struts

If your organization has enterprise applications that predate the Spring dominance, there's a reasonable chance some of them are running Apache Struts. Struts has had a complicated security history—it was the framework involved in the Equifax breach—and it has multiple EOL versions still running in production across large enterprises.

Struts is the kind of dependency that teams forget about until there's a CVE in the news. By then, it's too late to plan.

HeroDevs provides NES for Apache Struts, including ongoing security patches for versions that the Apache Software Foundation no longer supports.

Apache Tomcat 8.5

Tomcat 8.5 reached end of life in March 2024. It's the servlet container of choice for a huge portion of Java 8 enterprise applications—and it's now unpatched.

What makes Tomcat 8.5 particularly risky is that it sits at the infrastructure layer. A vulnerability in the application server affects every application running on it, not just one. A single unpatched Tomcat instance can be the entry point for a breach that touches multiple systems.

HeroDevs offers NES for Apache Tomcat 8.5, providing continued security patching for organizations that can't yet migrate to a supported version.

Hibernate 5

Hibernate 5 is the ORM layer for a massive portion of Java enterprise applications. It powered Spring Boot apps, standalone Java EE apps, and everything in between during the Java 8 era. Hibernate 5 is EOL and no longer receiving security updates from the Hibernate team.

ORM vulnerabilities tend to be severe when they occur—SQL injection, data exposure, authentication bypass. An unpatched ORM in a production application is a meaningful risk, particularly in compliance-sensitive environments.

Apache Camel, Apache Solr & Lucene, Apache Spark, and the Broader Apache Ecosystem

The Apache ecosystem was deeply intertwined with Java 8 enterprise development. Apache Camel (integration), Apache Solr and Lucene (search), Apache Spark (data processing)—these are all frameworks with EOL versions that correlate directly with Java 8 environments.

Teams running these frameworks often have the most complex migration paths, because they're not just updating a dependency—they're rearchitecting data pipelines, search infrastructure, and integration layers. That takes time. And during that time, the EOL versions they're running accumulate unpatched CVEs.

HeroDevs provides NES across the Apache ecosystem, covering multiple versions of these frameworks for organizations that need continued security coverage during extended migration timelines.

Why Compliance Makes This Urgent

Framework-level EOL isn't just a security problem. It's a compliance problem—and compliance doesn't negotiate.

PCI-DSS requires that all software components receive security patches. HIPAA requires risk management controls that include keeping software current or compensating controls for software that can't be updated. SOC 2 auditors look at whether your systems are running supported software. FedRAMP has explicit requirements around software lifecycle management.

Running EOL frameworks in production doesn't just mean you might get breached. It means you might fail your next audit. And "we're in the middle of migrating" is not a compensating control.

The standard compensating control for unsupported software is ongoing security patching from a third-party vendor—which is exactly what NES provides. It's not a workaround. It's the recognized path for maintaining compliance posture while executing a migration that can't happen overnight.

‍

The Hidden Vulnerability Problem

Here's something that doesn't get discussed enough: CVE reporting for EOL software is inconsistent.

When a security researcher discovers a vulnerability that affects both a current version and an EOL version of a framework, the CVE may only be assigned for the current version. Your security scanner looks for CVE assignments—if there's no CVE for the EOL version, the scanner reports clean. But the exploit still works.

This means that teams running EOL frameworks may have a false sense of security. Their tooling is telling them they're clean because nobody is formally tracking vulnerabilities against versions that are no longer supposed to be running in production. The actual exposure is invisible to standard scanning.

This is one of the core problems NES addresses. HeroDevs monitors the broader threat landscape—not just official CVE assignments—and patches vulnerabilities in EOL versions even when they're not being formally tracked by the upstream project.

What a Realistic Java 8 Migration Actually Looks Like

Migrating off Java 8 isn't a single task. It's a project portfolio. Here's what enterprise teams are typically dealing with:

JDK migration is the part everyone talks about. Moving from Java 8 to Java 17 or Java 21 or Java 25 involves language compatibility testing, build system updates, and runtime behavior changes. For large codebases, this alone is a 6–12 month effort.

Framework upgrades are the part nobody talks about enough. Spring 5 to Spring 6 is not a drop-in upgrade—it requires Jakarta EE namespace changes, deprecated API removal, and compatibility testing across every dependency. Struts migrations often involve partial application rewrites. Tomcat 8.5 to Tomcat 10 requires Jakarta EE migration by definition.

Dependency remediation is where migrations stall. You can't upgrade Spring until your third-party libraries support the new version. You can't upgrade Tomcat until your application server dependencies are compatible. Every slow-moving vendor in your dependency tree adds to your timeline.

Testing and validation always takes longer than estimated. Enterprise applications have integration points, legacy behaviors, and edge cases that don't surface until you're in a staging environment running the new stack.

A realistic Java 8 migration for a complex enterprise application takes 12–24 months from serious planning to production deployment. Teams that started planning in 2024 are in reasonable shape. Teams that haven't started yet are already behind.

What Smart Teams Are Doing Right Now

Audit the full stack, not just the JDK. Run a dependency audit across every production application. Identify not just what Java version you're on, but what versions of Spring, Hibernate, Tomcat, Struts, and Apache ecosystem frameworks you're running. Map each one against current EOL dates.

Triage by exposure, not by convenience. Applications facing compliance audits or handling sensitive data should be prioritized for migration regardless of complexity. The cost of a compliance failure or breach is higher than the cost of a difficult migration.

Build a realistic timeline—then add buffer. If your team estimates 12 months, plan for 18. Third-party vendor compatibility, unexpected breaking changes, and resource constraints will consume the difference.

Establish a security bridge for applications that can't migrate immediately. For every application that won't make a migration deadline, the question isn't how to migrate faster. It's how to stay secure and compliant while you take the time to migrate correctly. That's what NES is for.

FAQ

Does HeroDevs offer support for Java 8 itself?

HeroDevs does not currently offer NES for the Java 8 JDK. However, HeroDevs does offer NES for many of the frameworks and middleware components that run on Java 8, including Spring, Apache Struts, Apache Tomcat 8.5, Hibernate, Apache Camel, Apache Solr & Lucene, and Apache Spark. For organizations whose primary risk is in the framework layer rather than the JDK itself, NES covers a significant portion of the EOL exposure.

What's the difference between Java 8 extended support and what NES provides?

Oracle and third-party JDK vendors (Azul, Amazon Corretto, etc.) offer extended support for the Java 8 runtime. NES addresses a complementary problem: the EOL frameworks and middleware that run on top of the JDK. Most enterprise Java 8 applications are running multiple EOL components simultaneously. Extended JDK support alone doesn't patch Spring, Tomcat, or Struts.

Our security scanner isn't reporting vulnerabilities in our EOL frameworks. Does that mean we're safe?

Not necessarily. CVE reporting for EOL software is inconsistent—vulnerabilities affecting EOL versions may not receive formal CVE assignments even if the exploit is valid. HeroDevs monitors the broader threat landscape and patches vulnerabilities in NES-covered products even when they're not being formally tracked by upstream projects.

We're planning to migrate but it's going to take 18 months. Is NES the right fit?

Yes. NES is specifically designed for organizations with real migration timelines—teams that need more time to migrate correctly rather than quickly. NES provides continued security patching, CVE remediation, and compliance coverage for the duration of your migration, with no obligation to compress your timeline.

Which versions of these frameworks does HeroDevs support?

HeroDevs covers multiple EOL versions across Spring, Apache Struts, Apache Tomcat, Hibernate, Apache Camel, Apache Solr & Lucene, Apache Spark, and other frameworks. For specific version coverage, visit the HeroDevs supported products page or contact the team directly.

How does NES interact with compliance audits?

NES provides documentation and patch records that can be used as evidence in compliance audits. Third-party security patching from a recognized vendor is a standard compensating control for software that cannot be immediately migrated. HeroDevs can work with your compliance team to provide the documentation required for your specific framework (PCI-DSS, HIPAA, SOC 2, FedRAMP, etc.).
