Description Trevor Robinson CLA 2005-10-14 01:40:03 EDT 
I'm running 3.2 M2 (I20050923-1000) and I get this error on code that compiles
fine on javac and 3.1: "Type mismatch: cannot convert from Set<Object> to Set<?
extends SomeClassOrInterface>". The code in question generally looks like this:

    public Set< ? extends ConstructorModifier> getModifiers()
    {
        return Collections.emptySet();
    }

I'm not sure exactly when this broke, as I didn't try it with 3.2 M1, but it
worked in 3.1.
