This is Strange:
1.) I create a simple application called "Simple Test" using just "jpackage --type app-image --name "Simple Test" ... "
If I cd to "Simple Test.app" in the output directory and run command:
"Contents/MacOS/Simple Test" it runs fine.
2.) but if I cd to "Simple Test.app/Contents/MacOS: and just run "./Simple Test" I get the error:
Error opening ".../Simple Test.app/Contents/Contents/app/Simple Test.cfg"

3.) This problem originally reported in email:
After building with jdk15's jpackage the app fails to launch. The following appears in the system.log:

Jan 22 08:58:03 dharma com.apple.xpc.launchd[1] (org.mbari.vars.ui.101792[34511]): Service exited with abnormal code: 1

I launched the jlink built app and confirmed it runs as expected using:

cd "VARS Annotation.app/Contents/runtime/Contents/Home/bin"
./VARS\ Annotation

I attempted to run the jpackage built executable on the command line using:

cd "VARS Annotation.app/Contents/MacOS"
./VARS\ Annotation

It fails with the following message:

Error opening "[...]/VARS Annotation.app/Contents/Contents/app/VARS Annotation.cfg" file: No such
