Player able to spawn in the middle of the ocean

The bug (maybe?)

On at least one world seed, the default spawn point of the player is in the middle of an ocean with no land in sight. It is possible that this is not unintended behavior, but I find it unlikely that the game would at least check to make sure the player does not spawn on land.

How to reproduce

1. Open up Minecraft
2. Create a new world with the seed 4015
3. Generate the world

Observed result

The player spawns in the middle of the ocean.

Expected result

The player spawns on land.
