Generics implicit cast ?

Foo.java

import java.util.List;
import java.util.ArrayList;

public class Foo {
	
	public <T> List<T> getGenerics() {
		return new ArrayList<T>();
	}
	
	public <T> T getFoo() {
		return getGenerics().get(0); // Compilation error
	}
	
	public <T> T getBar() {
		List<T> bar = getGenerics();
		return bar.get(0); // OK
	}

	// AND THIS WORKS :

	public <T> T getGeneric() {
		return null; // we don't care, the problem happens at compilation time
	}

	public <T> T getFoobar() {
		return getGeneric(); // OK
	}
}
