I'm trying to replace some ancient SunOne directory servers with 389 DS. I have a brand spankin new CentOS installation where I followed the steps as outlined here. My workstation is RHEL7, where I installed 389-console for the purposes of connecting remotely to aforementioned new LDAP server.
However when I attempt to launch 389-console locally, I get a java.awt.HeadlessException error. I bounced around google abit and almost everyone else I've seen post this issue where experiencing the same issue only they where trying to forward 389-console over X.
I would expect that this would just launch locally with no issue and the errors appear to be related to remote connectivity:
mose@localhost ~ $ 389-console

I found in the debug trace, that despite update-alternatives being configured for oracle JRE, 389-console was using openJDK. While openJDK was installed, I only had the headless version of it which is not sufficient to run the AWT library
The problem is here:
Create this variable:
and run again:
