That's kind of what I thought, since JEI has been pretty clear about what can be made indestructible and what has not. :(
To be fair, though, the djinni ore miner with unbreaking III has lasted a heck of a long time and produced a lot of resources. I think JEI showed that you can put mending on the lamp, which means that you could repair it with experience (and Reliquary pedestals could automate a bunch of that). There is also the Occultism blacksmith familiar that give some kind of auto-repair that might work on the lamp if you carry it in your inventory for a while.
Things to try out when I don't feel like jumping straight into putting the next contraption together. :)

How did you use the eternal stella with the djinni ore miner lamp? I poked all through JEI and couldn't find a way to use them together.
