We are currently working through our first release of Eclipse Temurin and
will be updating this FAQ as and when things are completed and available.
If you want to talk to us or ask additional questions the best place is
our slack instance or via an
issue in the support
channel if your question is not covered by one of the entries below.
Most of the Eclipse Temurin builds with HotSpot for 8u302-b08, 11.0.12+7 and 16.0.2+7 are now available. Some
builds are not yet ready but we are working hard to get them ready.
You can follow progress via that table in
for the current status of each platform/version combination.
Unlike some of the releases which were performed at AdoptOpenJDK the
team is performing additional testing with brand new infrastructure
in order to be able to release
JDKs which means it is taking longer than usual to complete the
release cycle. We are unable to release on any individual
platform/version combination until this is complete. Please bear
with us - we are working very hard behind the scenes to make this
happen and the experiences we have gained should make the process
much quicker on future cycles.
Short answer: The project got so big that we chose to
move under the Eclipse
announced last year to provide us some additional stability for the future!
Longer answer: The builds you know as AdoptOpenJDK are now
"Eclipse Temurin by Adoptium"
blog post) Don't worry though - despite the branding changes it
is the same open build processes, AQAvit test suites and primarily the same team
producing them as before, but there are
more larger companies
now involved in the working group.
This is the project and brand name for the binaries that the Eclipse
Foundation produces. You can think of these as the successor
binaries to AdoptOpenJDK. However, it is important to note that
these binaries are just one of many that will eventually be in the
Eclipse Adoptium Marketplace. While we appreciate that the
Adoptium/Temurin name split is more confusing that just “Adoptium”,
this is similar to how other vendors brand their binaries, e.g.
Amazon has Corretto, Azul has Zulu (and others). The “Adoptium”
project and working group will deal with more than just Temurin so
the distinction is important to maintain.
We have already released most of the JREs for JDK8 but naturally
prioritised the full JDKs before doing those. For JDK11+ we would
generally recommend using jlink (see the
openjdk changes to stop building JREs by default) but despite that
statement we are currently aiming to release them for 11 as well for
continuity. We do not plan to do so for JDK16 and above. See
issue for discussion on the topic.
The transition to Adoptium means we have unfortunately not been able
to continue to distribute builds of Eclipse OpenJ9. IBM has now
taken them over and they are now available as "IBM
Semeru". There is no need to be concerned about the change - it
is still free.
Due to the limited amount of people we have working on the project,
maintaining the wide variety of docker images that we provided from
AdoptOpenJDK was becoming unsustainable. For that reason we are
releasing a cut down set of docker images for Temurin. For those
users who want a containerised Linux distribution that we don't
provide an image for, use
We are working on a solution for that at the moment with
issue as an umbrella for the work
This topic is something that has generated a bit of conversation
recently. We are currently considering our option but are leaning
towards headless musl-based builds for the JDK17 LTS release. If you
want to provide any input to that decision-making process, please get
There is a
new download API
provided by Adoptium for downloading Eclipse Temurin builds.
The good news is that it looks very like the AdoptOpenJDK one did so
migration isn't too difficult for anyone currently using it.￼
At present the AdoptOpenJDK API will redirect to
Temurin (or Semeru) if available when you request the latest release
builds. We have done this because we haven't had time to encourage
the community to fully migrate and because we haven't released
everything yet so there are missing builds in the Adoptium API. Note
that this will be a temporary measure and the
AdoptOpenJDK API is not expected to be retained forever to do this
although the timescale for removing the redirection is still to be
The people involved in the project are passionate about promoting it
and we are keen to find ways to promote the work we do at Adoptium
and with the Temurin binaries so feel free to get in touch with us if
you have a forum you wish us to participate in and we will see what
we can do. In general contacting the team via Slack is the best way
to engage with us.
