Eclipse Temurin End of Life (EOL) Dates & Support Timeline
Complete end-of-life dates, support windows, and security status for all Eclipse Temurin versions. Data from endoflife.date, checked against the vendor's own lifecycle pages where we have read them (share on /accuracy). Updated at every deploy.
Eclipse Temurin 27 is supported until March 2027, its end-of-support date. It is also the next Eclipse Temurin version to reach end of life. 8 of 14 tracked Eclipse Temurin versions are past end of life; the most recent to reach it, 26, did so on September 22, 2026. The full Eclipse Temurin lifecycle, with every version's release and end-of-support date, is in the table below.

Eclipse Temurin release and support pattern
Across the 14 release lines with a published release date, Eclipse Temurin has shipped a new line roughly every 6 months (median interval). A line typically stays supported for about 6 months from its release to its end-of-life date (measured on the 9 lines with both dates published). 5 of the 14 tracked lines are designated long-term support, which is where the longer windows sit.
Of the 14 release lines tracked, 8 are past end of life and 6 are still within support. The newest line, 27, was released September 22, 2026. The next scheduled end of life is 27 in March 2027 (the vendor names the month only).

What does Eclipse Temurin end of life mean for your organization?
When a version of Eclipse Temurin reaches end of life, the maintainers stop issuing security patches. Vulnerabilities discovered after this date are publicly disclosed on the National Vulnerability Database, exploit code appears on GitHub, and your systems remain permanently exposed.
The CVE blind spot: A CVE-based scan does not show the accumulation of unpatched vulnerabilities in EOL software. Some scanners flag unsupported versions of common products, but coverage varies, and none of them give you the date in advance. With a zero-day, nobody knows about the vulnerability. With EOL software, the vulnerability is public — listed, rated, and often weaponized — but no vendor patch is coming. This is one of the most dangerous gaps in enterprise security posture.
Organizations running EOL Eclipse Temurin should treat it as a vulnerability class in their risk register, apply compensating controls (network segmentation, enhanced monitoring, access restriction), and prioritize migration to a supported version.
Your options when Eclipse Temurin reaches end of life
There are four realistic paths. Which one is right depends far more on how long the system needs to keep running than on the version you are on today.
| Option | Best when | Watch out for |
|---|---|---|
| Move to a supported version | The system will outlive the current version's support window and you can schedule the work | Budget for compatibility testing, not just the upgrade itself — that is where the real cost sits |
| Replace the component | The project is unmaintained, or a better-supported alternative exists | The replacement has its own lifecycle and its own end-of-life date — you are changing vendors, not escaping the problem |
| Buy extended support | Migration is genuinely underway but cannot finish before the deadline, or the workload is frozen by certification or a third-party application | A bridge, not a destination — every year purchased is a year the migration still has to happen |
| Document accepted risk | The system is isolated, short-lived, or scheduled for retirement | Only defensible with real compensating controls and a written decision — auditors treat undocumented end-of-life software as a finding |
How to choose, in one question: how many more years does this system need to run? Under a year, extended support (where it exists) is usually cheaper than an emergency migration. One to three years, migrate — support purchased repeatedly costs more than doing the project once, and the project only gets harder as the version ages. Indefinitely, migrate now and plan the next migration before it surprises you.
Worth saying plainly, because vendors selling extended support rarely will: extended support is often the more expensive choice over a multi-year horizon. It is the right answer when a deadline is genuinely unreachable, not as a default. Compare the annual fee against the one-time cost of migrating before committing to either.

Extended Support Options
If you cannot migrate immediately, check whether the vendor or a third party sells extended support with security patches for your Eclipse Temurin version; coverage varies by product and version. Where it exists it is a bridge, not a permanent solution — plan your migration in parallel.
Eclipse Temurin has 8 versions past end of life — security patches have stopped, but CVE disclosures haven't. Extended support past the official date exists for many products in this position — whether it exists for Eclipse Temurin is exactly what we check. Tell us where to reach you and we'll reply with matched options and pricing guidance — or an honest "no vendor covers this."
