Obsidian generators currently do not work. Could be related to extremely slow liquids block updates (see other issue, lava currently takes 4 seconds to spread one block).
1) place lava bucket in dispenser
2) place redstone dust under the dispenser
3) place water in adjacent block
4) eject lava with dispenser

I know this isn't a bug, but I think there was no harm in the obsidian generator to begin with. I would think it no different from a cobblestone generator as far as how it was considered a bug, but those are just my thoughts.
Well, MC-58365 had an identical issue with an older version of Minecraft and it says in that one "Mojang said it was 'lucky bug become feature' ... but now obsidian generator (using water, lava and redstone/web) do not work."
So I had guesses IT WAS a feature now and it's broken in this build.
Obsidian Generators were a bug to begin with, and this was fixed a while back if I'm right 🙂
