We do not need to fix jpackage. It is already uses random mount root. Example from trace:

/usr/bin/hdiutil attach /var/folders/dr/65dj5x3j0296mqtsn9z27xc80000gn/T/jdk.jpackage8052723072987214442/dmg-workdir/proto.dmg -verbose -mountroot /var/folders/dr/65dj5x3j0296mqtsn9z27xc80000gn/T/jdk.jpackage8052723072987214442/dmg-workdir
