OSHI just pulls the value from the os.name system property, which comes from the JDK.

Latest JDK main branch correctly shows builds > 20347 as Server 2022.

That code was changed in September 2021 so I would think any recent JDK would have it backported.

We could put in a manual hack to do the same thing in OSHI (we do it for Windows 10 --> 11):

            if ("10".equals(version) && buildNumber.compareTo("22000") >= 0) {
                this.version = "11";
            } else {
                this.version = version;
            }

Or you can just update your JDK :)
