If the question is whether there is upstream source code of jdk13 for
mips, the answer is yes and they are
http://hg.openjdk.java.net/jdk/jdk13 and
http://hg.openjdk.java.net/jdk-updates/jdk13u. The zero of jdk13 works
on mips, but it is an interpreter version. If you are looking for an
upstream build, I think it is not available. Maybe you could find a
downstream build in some Linux distributions, like Debian.

Loongson maintains a mips64 port of jdk13, which is a server version.
We have released an ea build of jdk13 mips port [1]. It is built with
-march=loongson3a, so there would be problems if you run it on a
non-Loongson CPU.

The upstream mips port of jdk11 and jdk8 is in a similar situation to
jdk13. Only zero/interpreter is there.

We also maintain a mips64 port of jdk11u and jdk8u. We have not
released jdk11 yet. The repo of jdk8u could be found here [2]. The
latest jdk8u build could be found here [3]. It is also built with
-march=loongson3a.

I think Dalibor Topic is the right one to edit the page. However, in
my opinion, the source code position is the same as the other port,
and there is no download link, so nothing could be shown at
https://openjdk.java.net/projects/mips-port :)
