jpackage --dmg produces disk image with icons not positioned correctly/missing

ADDITIONAL SYSTEM INFORMATION :
Mac OS X 10.15.5

openjdk 16-ea 2021-03-16

A DESCRIPTION OF THE PROBLEM :
When jpackage is used to produce a .dmg, the /Applications alias does not get placed in the disk image and the hidden folders are not placed outside of the bounds of the window. It would appear that the dmg-setup.scpt fails with Finder reporting an error.

There is the same problem in jdk15.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run a command similar to the following:
jpackage --type dmg --app-image /Users/davidjlgradwell/NetBeansDev/PKBAnt/jpackageappimageoutput/PKB.app --name PKBInstaller --dest /Users/davidjlgradwell/NetBeansDev/PKBAnt/jpackagedmgoutputTest3 --resource-dir /Users/davidjlgradwell/NetBeansDev/PKBAnt/resources --verbose
Open disk image produced and examine.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Both the new application's icon and the /Applications alias icon should show in an appropriate place. The hidden icons should be positioned outside the visible window so that they are not visible to the user even if they have "Show hidden files" turned on.
ACTUAL -
The /Applications icon is not written to the disk image and hence does not appear. It would seem that the dmg-setup.scpt fails. The relevant part of the --verbose output is
