      Description

      /summon Boat ~ ~ ~ {Riding:{id:Villager,Riding:{id:MinecartRideable}}}

      This works fine.

      /summon SomeFakeEntitiy ~ ~ ~ {Riding:{id:Villager,Riding:{id:MinecartRideable}}}

      This gives a logical error message and a command-line warning (no stacktrace), and cancels summoning.

      /summon Boat ~ ~ ~ {Riding:{id:Villager,Riding:{id:SomeFakeEntity}}}

      This gives no error message error message and a command-line warning (no stacktrace), and summons a entity.

      /summon Boat ~ ~ ~ {Riding:{id:SomeFakeEntity,Riding:{id:MinecartRideable}}}

      This gives a general error and a stacktrace, but doesn't cancel summoning.
      Stacktrace:
