Generics unchecked assignment

I'm starting to apply generics to some code.
In this example:
new ArrayList( classroom.getStudentSet() )
The most generic way of using generics is
new ArrayList<Object>( classroom.getStudentSet() )
This causes "Unchecked assignment: '
' to '
>'". Can this warning be resolved without modifying the classroom class?

If classroom.getStudentSet() returns just a Set, without generics, then no. The only thing to do is either change the classroom class, or use @SuppressWarnings("unchecked") on that variable or the method/constructor.
