AdoptOpenJDK: Releases October 2020

What’s This About?

AdoptOpenJDK released minor updates to its two JDK LTS releases (8 and 11) and the current version (15). These updates are for both the HotSpot VM and the Eclipse OpenJ9 ones.

What’s in the Release?

The releases have security fixes: JDK 8, JDK 11, and JDK 15. Each release also has a new feature:

• OpenJDK 8: TLS 1.3 got backported. This is the technology that underlies HTTPS connections.
• OpenJDK 11: The Shenandoah garbage collector was backported. This was a controversial decision. Now all OpenJDK distributions have to support a new garbage collector that potentially changes the behaviour of Java applications.
• OpenJDK 15: It runs on CentOS/RHEL 6 again.

Should I Upgrade?

An unqualified yes for JDK 8 and 15. It’s a maybe for JDK 11. If you want to use the new Shenandoah garbage collector then, then please evaluate it to see if it’s right for you.

Where Can I Get It?

You can get all these JDK releases on the AdoptOpenJDK release page.

When Will the Next JDK Versions Be Out?

We expect JDK 16 in March 2021 and JDK 17, as the next LTS release, in September 2021.
