      Description

      Hostile mobs spawn on the surface despite light levels over 7.

       

      Testing methodology:  Create a new superflat world.  To avoid slime spawns, I set dirt height to 64, though the effect happens at the default setting of 2. 

      Observation: Despite being day, hostile mobs spawn on the surface.  This also happens inside well lit closed areas as well (see attachment).
