Third level of flowing lava will not create cobblestone when coming into contact with water

Cobblestone is only created if lava flows horizontaly into water.
"If water flows horizontally into lava, a hiss and puff of smoke occur but nothing changes." More information here

Was this marked as WAI because of what the wiki says? The wiki documents behavior, it does not say what is intended. Either way, water running horizontally into water will also create cobblestone, though this might have been a change made after this report was created: http://i.imgur.com/yArVkkf.png http://i.imgur.com/qpAymim.png

However, I believe this bug report was misunderstood. What it's actually about is the third (and last, in the overworld) level of flowing lava will not create cobblestone when coming into contact with water, see attached screenshots. So, please re-open and confirm for 1.8.

Reopened and changed Reporter.
If original reporter wants the ticket back, post it here.

It's only forming cobble when the water/lava is overriding the water/lava, as in trying to flow over to the block the other liquid is currently in, causing it to be both replaced with cobble, in this case, the liquids wont override each other but just touch both ends, which indeed cant form a block but probably should if you look at the logic behind it.

That is a different issue, Fabian. This issue is about horizontally flowing liquids. I suggest you create a new ticket for that situation.

No, almost half of all duplicates of this report are about exactly that: MC-18659, MC-19170, MC-19580, MC-38489, MC-44069, MC-44539, MC-51562, MC-82024, MC-97933, MC-124272, MC-126547, MC-154657.

They are the same bug
It being horizontal or vertical doesn't matter

In the code, lava checks for water nearby then converts to cobblestone
But after checking and finding water
It then checks if the lava level is at or below level 5
If so, converts to cobblestone
The furthest (lowest) lava in the overworld is 6, which is not at or below 5, so it doesn't convert
Changing the value from 5 to 6 fixes this bug

Water does no checking of its own

That it says it in the code doesn't make it not a bug. Of course every bug can be found in the code, that's why it happens at all.

But you can't really argue that water simply stopping in mid-air and not trying to flow either downwards or to the side is not a bug. It goes against every other mechanic of water physics.
