A DESCRIPTION OF THE PROBLEM :
When the jpackage tool creates an .app bundle and is fed a folder structure as input, it doesn't correctly mirror the input structure. Empty source folders are skipped.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Simply create an .app bundle using jpackage and use -i to refer to a folder containing sub folders, some being empty.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Target "Contents/Java" sub folder of generated .app bundle should mirror the structure passed in the -i argument to jpackage.
ACTUAL -
Empty folders in source structure are omitted.

CUSTOMER SUBMITTED WORKAROUND :
I copy the folder structure again to the generated .app bundle after running jpackage.

FREQUENCY : always
