Running applications on ports lower than 1024 in Linux requires root or other types of escalated privileges. Since Java runs in a VM, it will not be able to SUID easily after starting as root.

The recommended way is to leave it run on the current port, on localhost, and put a reverse proxy in front of it (such as nginx or - easier, haproxy).
