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.
