I haven’t tried this yet. It means invoking jpackage indicating a earlier jdk. I can do this. Since I’ve sort of gathered 17 and 18 changes are sort of going in parallel right now I’ll try to go back to 16.

I think the actual nature of the error could be indicated without revealing the location of the files. 

The current jpackage invocation follows…
