jpackage --create-installer problem on Mac when installer-type is unspecified

[Lennart Börjeson]

While the EA build 30 seems to solve my Mac problems, there still seems to be a similar problem on Linux:

Succeeded in building RPM Bundle bundle
jdk.jpackage.internal.PackagerException: Bundler DEB Installer skipped because of a configuration problem: Can not find dpkg-deb.  
Advice to fix: Please install required packages.

After which jpackage exits with error 255.
