How is Oracle Java 6 Licensed?
Oracle Java 6, also known as Java SE 6, was one of Oracle’s most popular Java releases, widely adopted across enterprise and government sectors.
However, understanding how Java 6 is licensed today can be complex, especially given Oracle’s licensing shifts in recent years.
This article comprehensively breaks down:
- Java 6 licensing history.
- Current licensing structure and implications.
- Security updates and patches.
- Risks associated with continued Java 6 use.
- Strategic recommendations and practical alternatives.
Java 6 Licensing: A Brief History
To fully grasp current licensing implications, it’s helpful to understand Java 6’s licensing evolution clearly.
Initial Release and Licensing (2006-2013)
Sun Microsystems released Oracle Java 6 in December 2006. At the time, Java was distributed freely under the Sun Binary Code License (BCL), allowing broad commercial and personal use at no cost.
Key highlights of Java 6 licensing during this initial phase:
- Free commercial use: Businesses could download and deploy Java 6 in development and production.
- Regular free security updates: Sun Microsystems (later Oracle after acquiring Sun in 2010) provided regular security updates without subscription charges.
Oracle’s Acquisition and Licensing Adjustments (2010 onwards)
Oracle acquired Sun Microsystems in January 2010, inheriting Java SE licensing. Initially, Oracle continued the free licensing model under the Oracle Binary Code License (BCL), similar to Sun’s previous terms.
However, significant changes occurred starting in 2013 when Java 6 reached End-of-Public-Updates:
- Oracle officially ended free public security updates for Java 6 in February 2013.
- Companies wanting further Java 6 security patches needed to subscribe to Oracle’s paid support services, specifically the Oracle Java SE Extended Support.
From this point onward, Java 6 usage without subscription posed significant security and compliance risks.
Understanding Java 6 Extended Support Licensing
After February 2013, Oracle’s Java 6 entered the “Extended Support” phase.
What Does Oracle Java SE Extended Support Provide?
Oracle Java SE Extended Support provided organizations with:
- Continued critical security updates beyond the public update period.
- Bug fixes and patches are available exclusively to subscribers.
- Access to Oracle’s premium technical support channels.
How Oracle Java SE Extended Support is Licensed
Oracle’s Extended Support for Java SE is typically licensed under two main metrics:
- Processor-based Licensing: Charged per physical processor or core in servers running Java.
- Named User Plus (NUP): Charged per individual user accessing applications powered by Java 6.
Typical subscription pricing (approximate):
- Processor License: Roughly $300 per processor/year.
- Named User Plus License: Approximately $30 per user/year.
Example Scenario of Licensing Cost
Consider a financial institution running Java 6 on 10 servers, each server equipped with two processors (20 processors total):
- Annual Licensing Cost: 20 processors × $300 = $6,000 annually.
This illustrates how continued Java 6 licensing under Extended Support significantly increased organizational costs.

Security Patches and Updates for Oracle Java 6
Security updates for Java 6 followed two distinct phases:
Phase 1: Public Updates (Until February 2013)
Oracle released regular public security patches and updates at no cost until February 2013. Companies could freely download and apply these patches without licensing obligations.
Phase 2: Extended Support (Post-February 2013)
Starting in February 2013, public updates ceased. Security updates and patches became available only to Oracle Java SE Extended Support subscribers. Non-subscribers had no legal means of accessing these security patches from Oracle.
Key Java 6 Security Update Milestones:
| Java 6 Update Version | Release Date | Licensing Requirement |
|---|---|---|
| Java 6u43 | February 2013 | Final free public update |
| Java 6u45 | April 2013 | Extended Support (Paid) |
| Subsequent Updates | Post-April 2013 | Extended Support (Paid only) |
Businesses running Java 6 commercially without Extended Support after February 2013 exposed themselves to severe security vulnerabilities and compliance risks.
Risks Associated with Continued Use of Java 6 Without Licensing
Organizations opting to use Java 6 without an Extended Support subscription faced numerous critical risks:
Security Vulnerabilities
- The absence of patches makes Java 6 increasingly vulnerable to security threats and exploits.
- There is a high likelihood of targeted cyber-attacks exploiting unpatched vulnerabilities.
Compliance and Regulatory Risks
- Regulated industries (finance, healthcare, government) have strict compliance requirements for maintaining patched, supported software versions.
- Regulatory bodies frequently require documented evidence of software support and patching activities.
Oracle Licensing Audits
- Oracle actively audits enterprises for software compliance.
- Organizations found using Java 6 without a proper Extended Support license risk significant fines, back payments, and costly audits.
Real-World Example of Risk
In one notable example, Oracle audited a retail company in 2017. Oracle discovered extensive commercial Java 6 usage without Extended Support subscriptions, which resulted in substantial retroactive licensing fees, penalties, and expensive remediation efforts.
Strategic Alternatives to Java 6 Licensing
Given the high costs and risks of continuing Java 6 licensing under Extended Support, organizations must evaluate alternative paths:
Option A: Upgrade to a Newer Java Version
- Move applications to newer Oracle Java versions (e.g., Java 17 or newer).
- Initially, it requires effort, compatibility testing, and possible code refactoring.
- Provides access to ongoing free or lower-cost support options.
Option B: Migrate to an Alternative Java Distribution
- Alternatives like OpenJDK, Amazon Corretto, Azul Zulu, or Eclipse Temurin offer free, robust, community-supported updates.
- Eliminates Oracle licensing costs while maintaining security compliance.
- Typically requires minor code modifications and compatibility validation.
Option C: Decommission or Replace Legacy Java 6 Applications
- Completely phase out legacy Java 6-dependent applications.
- Replace or modernize older applications with newer technologies.
- A strategic long-term solution eliminates Java 6 related licensing risks permanently.
Practical Example of Successful Migration
A large government agency successfully transitioned legacy Java 6 applications to Amazon Corretto, fully eliminating Oracle licensing costs and significantly reducing security risks.
Frequently Asked Questions (FAQs)
Is Java 6 still free for commercial use today?
- No. Java 6 free public updates ended in February 2013. Commercial use today requires Oracle’s Extended Support subscription for security patches and updates.
What happens if I use Java 6 without paying Oracle’s subscription fees?
- Significant security vulnerabilities, high compliance risks, and potential Oracle licensing audits with costly penalties.
Can I legally obtain Java 6 security patches today without paying?
- No. Security patches post-February 2013 require an Oracle Java SE Extended Support subscription.
What alternatives exist to paying Oracle for Java 6?
- Upgrade to newer Java versions (Oracle Java 17+).
- Migrate to alternative Java distributions (e.g., OpenJDK, Amazon Corretto, Azul Zulu).
Strategic Recommendations for Businesses Still Using Java 6
Given Java 6’s current licensing structure, clearly recommended actions include:
- Conduct Immediate Java Audit:
Identify all Java 6 deployments across your enterprise clearly and thoroughly. - Assess Extended Support Costs and Risks:
Carefully evaluate Oracle subscription expenses against potential security and compliance risks. - Develop a Proactive Migration Strategy:
Migrate to newer Java versions or open-source distributions to permanently resolve licensing issues. - Maintain Thorough Licensing Records:
Document all Java licensing, deployments, and migrations to mitigate audit risks effectively.
Conclusion: Navigating Java 6 Licensing Today
Oracle Java 6 licensing transitioned from a free public update model to paid Extended Support after February 2013. Today, continuing Java 6 without subscription licensing is fraught with severe compliance and security risks.
Organizations benefit from proactive strategic decisions to migrate to newer Java versions or alternative distributions, significantly reducing licensing costs, eliminating compliance concerns, and enhancing security. Proactive Java licensing management remains critical for controlling risks and optimizing IT expenditures in modern enterprises.
