Testing variance in Java's generics. Why on earth doesn't this compile? In IntelliJ, getClass on line 13 errors as 'cannot resolve symbol' Javac doesn't produce a logical error.

Type variance test

public class GenericVariance {

    class A {}
    class B extends A {}

    @Test
    public void checkTypes() {
        assertTrue(new B() instanceof A);

        final List<A> listOfA = new ArrayList<>();
        final List<B> listOfB = new ArrayList<>();

        assertFalse(listOfB instanceof listOfA.getClass());
    }
}
