use getClassName at keyIndex creation so that it can be found with other...

I'm not really a Java guy :).  However, when you create a KeyIndex, you're using just the ic.className, but in the other methods you use getClassName method.  I *think* this is wrong, but again - I'm hardly a Java guy... and there could be another reason why that's *right*.

What I'm trying to fix is that when you create a KeyIndex, you cannot use the getIndexedKeys method.
