The SMC server on Solaris 8 and 9 — a remote system-administration listener.
Solaris Management Console ran a Java server process on port 898, and Oracle's own troubleshooting documentation shows the status output "SMC server version 2.1.0 running on port 898" and the matching "Shutting down SMC server on port 898". Administrators used the SMC GUI against it to manage users, filesystems, cron jobs and other host configuration. It is not IANA-registered; 898 is Sun's convention, and Nmap identifies it as the Solaris Management Console Java listener. Finding it open means a Solaris 8 or 9 host, long past support, still exposing its admin plane.
Do not expose
A remote system-administration service on an end-of-life OS; keep it off any routable interface and prefer disabling it entirely.
