The current PR seems a point fix, but do we need to update other logic - e.g. version recognition to identify and report that we are running on NanoServer?

Agreed, noting that previous OpenJDK versions have worked just fine in a Nanoserver environment. This was broken by the newly introduced dependency on kernel32.dll. I've refactored the code now to check the registry to determine if the host OS is a nanoserver variant. This will mean that we can rely on the isNanoServer check in other places in the future where required. As things stand this is enough to get Java working again
