Definitely an ongoing bug, it seems.
UA Insider may know what's going on.
Channa, nice try.

It's been reported this has been showing on international flights as well, and Jeff would never eliminate meals in J. Definitely a bug. But, yeah, it would be a big hint if it was only showing for domestic flights.
Edit: I did a test flight status for EWR-LHR (7/14/2011, 7:25pm). Here's what's posted:
Food:
BusinessFirst: Beverage
Main Cabin: Hot meal featuring a choice of three main course options and a pre-arrival snack
So it definitely is a bug.
