My current understanding is this. Including native commands with an OS X application with an embedded JRE does not work at all for current applications/JRE’s.

I’m not sure what the application problem with jlink was last night but it is working tonight. From the earlier problems with Eclipse I still had jdk14 removed from JavaVirtualMachines. The version command started indicating jdk13. I put 14 back in and built a current jpackage application with a jlink commands included runtime. 
I then again removed jdk14 from JavaVirtualMachines.

exec java -version
openjdk version "13-internal" 2019-09-17
OpenJDK Runtime Environment (build 13-internal+0-jdk13-jpackage.49)
OpenJDK 64-Bit Server VM (build 13-internal+0-jdk13-jpackage.49, mixed mode, sharing)
versions
System.in:3:java.version=14
System.in:5:java.version.date=2020-03-17
System.in:15:java.class.version=58.0
System.in:16:java.vm.specification.version=14
System.in:19:java.vm.version=14+36-1461
System.in:22:java.runtime.version=14+36-1461
System.in:25:java.specification.version=14

It only finds the command in the JavaVirtualMachines 13 runtime. Not the application included 14 one. 
It only works if the OS has a correct link in place

exec which java
/usr/bin/java
exec ls -l /usr/bin/java
lrwxr-xr-x  1 root  wheel  74 Mar 19  2019 /usr/bin/java -> /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java

It does not work for jlink or jpackage because no such link exists.

Currently, at least for Runtime exec including the commands with the application does no good.
