Funny you should mention this. I regularly use the gas pumps at our local chain grocery store (Kroger) at two different locations; one with old pumps and one with new pumps. Originally the displays were very snappy and I could get in and out pretty quickly. About a year ago they updated the software on the "new" pumps and it got very, very slow (along with some questionable font choices). It was so bad that I went out of my way to visit the "old" pumps more frequently. Unfortunately, the old pumps were eventually "upgraded" and I now have to deal with crappy gas pump software everywhere. So, I don't think it's based on the age of the pump. I'm guessing that there is a pretty standard architecture that they all adhere to. So yeah, I bet they run Java. BTW: I've noticed this same thing with ATM software. I'm pretty sure they run Java as well.
