Comment (by breun):

 If the app already contains an entire JRE, then I think it won't be
 necessary to have the `openjdk8` port installed. I'm not very familiar
 with macOS GUI apps that use Java, but I guess the .app must contain some
 kind of start script that starts the `java` process with the correct
 arguments. Maybe you can take a look at the package contents of another
 macOS GUI app on how to do this. Dealing with the `JAVA_HOME` environment
 variable indeed shouldn't be necessary in this case.
