Description
jpackage --app-image /tmp does not provide a helpful message with a malformed app-image.

Example 1:
 jpackage --app-image /tmp --package-type deb  --output x

Output:
Bundler DEB Installer skipped because of a configuration problem: java.lang.NullPointerException.

Example 2:
jpackage --app-image /tmp

Output:
Error: Option [--app-image] is not valid with package-type [null].

Example 3:
mkdir /tmp/x
touch /tmp/x/y
jpackage --app-image /tmp/x --package-type deb  --output x --name xxxx

Output 3:
java.nio.file.NoSuchFileException: /tmp/jdk.jpackage13842042862336393495/images/linux-deb.image/xxxx-1.0/opt/xxxx/bin/xxxx.png

Example 4:  (Even with a well formed app image) if the --name is missing the message is poor.
jpackage -o out --app-image out/skara --package-type deb

Output 4:
Bundler DEB Installer skipped because of a configuration problem: java.lang.NullPointerException.

Fix request [21u] I backport this for parity with 21.0.7-oracle. No risk, only a test change Clean backport. Test passes. SAP nightly testing passed.

JDK22 jpackage handles described use cases better: ~$ ./jdk-22/bin/jpackage --app-image /tmp --type deb --dest x Error: Missing .jpackage.xml file in app-image dir "/tmp" ~$ ./jdk-22/bin/jpackage --app-image /tmp Error: Missing .jpackage.xml file in app-image dir "/tmp" ~$ mkdir /tmp/x; touch /tmp/x/y ~$ ./jdk-22/bin/jpackage --app-image /tmp/x --type deb --dest x --name foo Error: Missing .jpackage.xml file in app-image dir "/tmp/x" ~$ ./jdk-22/bin/jpackage --app-image /tmp/x2 --type deb --dest x --name foo Error: App image directory "/tmp/x2" does not exist Still, makes sense to add relevant tests.
