Subject: Solaris Support in OpenJDK 21?

Hi,

I understand that Solaris and SPARC ports were deprecated in JDK 15 and removed afterward (JEP 381).

However, I would like to ask if there are any community efforts, backports, or plans to support OpenJDK 21 on Solaris (SPARC or x86), even unofficially.

If not, is building from source still feasible with some patching?

Thank you in advance for your guidance.

Best regards,
Hyejin

Hi Hyejin,

I believe Peter keeps an unofficial port of Solaris (Both SPARC and
x86) around and maintains them. I'm not sure what the best way to
query about the state of the port is however, since it seems to
entirely be resting upon the shoulders of one person and as a result
not many would know about specific details of the efforts to keep
Solaris Java up and running. The closest thing I can find about the
Solaris port is the blog at
https://ptribble.blogspot.com/2021/12/keeping-java-alive-on-illumos.html

best regards,
Julian

Yes. I maintain an out of tree port to Solaris and illumos, scripts and
patches are here:

https://github.com/ptribble/jdk-sunos-builder
https://github.com/ptribble/jdk-sunos-patches

and binaries are also available:

https://pkgs.tribblix.org/openjdk/intel-solaris/
https://pkgs.tribblix.org/openjdk/sparc-solaris/

The x86 port is current and works extremely well; I'll have jdk25 builds
available when
it's released.

SPARC is a little trickier (with x86 the architecture itself is supported
in mainline jdk,
and Solaris is just a regular unix so the port is easy - SPARC is really
quite odd and
unsupported in mainline so is much harder). The jdk17 builds work extremely
well for a
lot of cases - they run the Jenkins agent just fine, for instance - but
have a habit of
crashing under load. To try and fix those problems, or push the SPARC port
past jdk18,
would be a fairly significant undertaking and I currently have neither time
nor funding to
make it happen.
