[jpackage] JDK25 no longer takes into account --mac-package-identifier

[Alexey Semenyuk]

Hi Daniel,

I can not reproduce the issue you experience with jdk25.0.1:

---
$ ~/jdk-25.0.1.jdk/Contents/Home/bin/jpackage --input input --dest 
output --type app-image --main-jar hello.jar --main-class 
com.my_domain.project.Hello --mac-package-identifier com.my-domain.project
$ echo $?
0
---

If I run the same command line without ` --mac-package-identifier` 
option it fails as expected:
---
$ ~/jdk-25.0.1.jdk/Contents/Home/bin/jpackage --input input --dest 
output --type app-image --main-jar hello.jar --main-class 
com.my_domain.project.Hello
Bundler Mac Application Image skipped because of a configuration 
problem: invalid mac bundle identifier [com.my_domain.project].
Advice to fix: specify identifier with "--mac-package-identifier".
---

The same failure for `--mac-package-identifier com.my_domain.project` 
(with the underscore):
---
$ ~/jdk-25.0.1.jdk/Contents/Home/bin/jpackage --input input --dest 
output --type app-image --main-jar hello.jar --main-class 
com.my_domain.project.Hello --mac-package-identifier com.my_domain.project
Bundler Mac Application Image skipped because of a configuration 
problem: invalid mac bundle identifier [com.my_domain.project].
Advice to fix: specify identifier with "--mac-package-identifier".
---

Any chance you accidentally put the string with the underscore instead 
of the hyphen as a value of the `--mac-package-identifier` option on 
your command line?
