This method is legal according to the JLS (15.12.2.8) and compiles with 3.1.0:

  public List<? extends String> getList() {
    return Collections.emptyList();
  }

In 3.1.1 build M20050929-0840 it gives the following error:

  Type mismatch: cannot convert from List<Object> 
    to List<? extends String>

If the method returns List<String> there is no problem.
