Nested wildcard is strange

843793Aug 14 2006 — edited Aug 25 2006

Hi,

I know that I can create something like this

List<?> myList = new ArrayList<Object>();

And now I want to use this in a Map

Map<String, List<?>> myMap = new HashMap<String, List<Object>>();

But the compiler complains about "Type mismatch: Cannot convert..."

Allowed is this

Map<String, List<?>> myMap = new HashMap<String, List<?>>();

Can someone explain this to me?
