Mac gave me the 9 commands shown earlier. Something inconsistent involved?

I was trying a couple of these options for something unrelated last night. Just a quick look not extensive. But it seemed like if you copy —runtime-image you are limited in making some modular changes to that runtime. I also tried directly using jlink to make the runtime myself but that also errored. I didn’t make any effort to figure out the problem at that time. A linkage error of some sort in class initialization for my launcher class. 
Manually changing a copied runtime I didn’t try. You could then just copy the commands you need to the jpackage runtime if the application is unsigned? I used to do something similar for app’s that needed an embedded ‘java’ command available. But got scolded for doing so when I mentioned it on this list. 

If the functionality is critical to the app I will probably have to make one of those options work. Currently it isn’t critical. So I guess I could just add an availability check.

Thanks.
