Thanks for looking into this.  Your analysis is great.

It may be my fault.  I'm guessing I made this change and then forgot
to remove the native methods.  Not sure though.

With the indentation fixlets the patch is fine to check in.  I can put
it in Classpath if you want; just send me the updated patch (privately
is fine).
