AdoptOpenJDK: Releases January 2021

What’s This About?

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

What’s in the Release?

The releases have “security fixes and other fixes”: JDK 8u282, JDK 11.0.10, JDK 15.0.2, and Eclipse OpenJ9.

The releases have one new feature: Their trust stores now has the same trusted CA (certificate authority) certificates as Mozilla Firefox. Java uses these certificates to validate server certificates in HTTPS connections.

These release also took away one feature: Only Linux, the font library Freetype isn’t bundled anymore. Why? Probably because OpenJDK doesn’t bundle Freetype anymore, either. Check this article for dealing with fonts in OpenJDK.

Should I Upgrade?

An unqualified yes.

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. JDK 17, probably the next LTS release, is scheduled for September 2021.

Java Tech Popularity Index Q1/2024:
Developer job ads down 32% year over year, Stack Overflow questions dropped 55% since ChatGPT. I now recommend IntelliJ Community Edition because many AI code assistants don't run in Eclipse. Job ads for Quarkus hit an all-time high.
