Searching for unnecessary typecasts

Question

Are there any tools that can read my code and find unnecessary typecasts?
I'm in the process of upgrading all my code to use generics. I'm very pleased at the number of typecasts I'm eliminating. Since I'm doing it manually, though, I bet I'm leaving in a lot of unnecessary (and potentially unsafe) casts. It would be great to have to tool that would find all these.

You're asking if the compiler will complain when I
make a necessary cast? Of course not.In 1.5, don't you get a warning about an unsafe cast?
The only time it wouldn't do that in 1.5 is if you
didn't really need the cast, right? Maybe, I'm
missing something.Ooops. Let me try that again...
I see. You 're talking about unsafe casts. I'm talking unnecessary. I've got tons of code that does something like this:
        ArrayList colors;
        return (Color) colors.get(0); // Casts from Object to Color.In moving to 1.5 I'm making the container generic.
        ArrayList<Color> colors;
        return (Color) colors.get(0); // Casts from Color to Color.  Unneeded. I wanted these compiler warnings to be tell me that the cast there is unnecessary and should be removed.
        ArrayList<Color> colors;
        return colors.get(0); // No cast. Joy.
