Just updated CAREO to WebObjects 5.2.3 (and MacOSX Server 10.3.3, Java 1.4.2). All appears to have gone well, except the WebObjects StartupItem got eaten. Empty. nada.
I copied the working one over from my laptop, and all's well. Caveat emptor. Yadda yadda.
UPDATE: Yup. Just updated commons.ucalgary.ca, and it borked the WebObjects StartupItem as well. I had tarred the previous one, so it was just a matter of tar -xf WebObjects.tar to get it back, but it makes me wonder what else might be messed up...
For the record, I applied the update to 3 machines (my test iMac, CAREO, and Commons), and the StartupItem was erased on all 3. Everything else appears to be OK, though...
UPDATE 2: Filed it in Radar, as bug #3591338
