Why can I not filter a List<EntityLivingBase> in Minecraft 1.12.2

So I need to get the list of entities that are loaded(Cows Chickens, Pigs etc) and I need to filter my list down to only entities that are of class "EntityLivingBase"

But I get a error saying "Cannot cast from List<Entity> to List<EntityLivingBase>"

Anyways here is my code if someone could help me.

List<EntityLivingBase> targets = (List<EntityLivingBase>) mc.world.loadedEntityList.stream().filter(EntityLivingBase.class::isInstance).collect(Collectors.toList());

Thank you in before hand!
