I tried switching to JDK 8 & used the latest code (tag: r1424) to build the jtrac.war but the exception remains.

[Ulf Dittmer]

I can't reproduce this. Starting with an empty database, I created 4 users, and had no issues assigning users to them either directly after creating a new space, or later on through the menu (using Adoptium 11 on macOS).

[Aejaz Muslim]

Sorry for the late reply. I found that this happens only with the user which has an ADMIN role only. As soon as a DEFAULT role is assigned to this user, the exception doesn't happen.

[Ulf Dittmer]

Nope, can't reproduce it with admin users, either.

I'd need the exact sequence of steps that led to the exception in order to investigate this.
