Why ignoring type safety warnings is bad
View ListsAreNotCovariant.java
List<Foo> specialThings = Lists.newArrayList(); //Foo extends Base
Bean bean = new Bean();
// normally you would correctly get a compile error here,
//but the setter in your example does an unsafe cast that makes this line compile
bean.setStuff(specialThings);
List<Base> things = bean.getStuff();
things.add(new Bar()); // Bar extends Base
