Ocean related biomes don't generate correctly in custom worlds

Since the bug of the water generating around Ocean Temples was fixed, I made a world to take a look, I discovered that no water generated, actually, a forest did. I tested this with Deep Ocean biome and the Frozen Ocean biome. At first I left the Ocean Monument to 'yes' in the customization menu. That's when it happened. Water level was set to '1'. In the pictures are the seeds of the worlds I tested on. In the FrozenOcean biome a kind of Forest/Taiga something appeared to form.

UPDATE: It seems that this bug does not affect 1.8.2-pre6 and earlier.
