I don't think so. As the types are erased at run time all we see is a method
with signature foo(List list). I think if you tried to add two methods to a
class:
public void foo(List<Long> x) { }
public void foo(List<Integer> x) { }
then javac would refuse to compile it saying that both have the same erasure.
