oxTrust: "System error" upon attempt to create user via oxTrust on freshly installed instance

Environment: Ubuntu 14.04, Gluu CE 2.4.4 SP2 (installed from gluu-server-2.4.4.2_6-1~trusty+Ub14.04_amd64.deb of 2016-11-07 (which is the latest available stable package))

Steps to reproduce:

1. Log in to web UI as admin user
2. Move to “Users -> Add person”
3. Fill in all fields on the page required to create a simple user entry with default fields; provide “active” for “User status” field (for some reason there is no drop-down list to choose value from)
4. Click the “Update” button to finalize the creation.

Result: “System error” message appears, user is not created, java exception is logged to wrapper.log (please see full text here):
