No, I haven't tried the other apps yet. I've only ever used the GUI and the command-line. I'll try that soon.

Meanwhile, here's some Java error traces from launching the GUI.

Hm, I couldn’t reproduce this out of the box. Does the problem only
occur in your GUI instance? Did you check out the behavior on
command-line or in the DBA as well?

I hit "GC" several times but it didn't seem to help. I had no database loaded/open. Seems like some memory isn't getting freed properly.
