Default Ch 12 QuickSort too much calls to doSort()?

In listing 12-4, method getPivotPoint does a call to
doSort(first, end-1)
I feel this call isn't needed at all. If I remove it from the code, the sorting still works.

Also, listing 12-4 contains 3 calls to doSort while the non generic version in listing 12-2 only contains two calls. I think that in listing 12-4, the two recursive calls inside method doSort itself are all you need.

Default Redundant call?

You're right...it does work fine on both even and odd numbers of items without the call to doSort(). Quite honestly, I've slept since I wrote this code and have no idea why I put it in there!
