Arrays.sort() inconsistent in which variant of DualPivotQuicksort.sort() is invoked

[Buis, Paul]

Arrays.sort(byte[]) and Array.sort(byte[], int, int) both invoke the 3 argument version of DualPivotQuickSort.sort() when  Arrays.sort() for all other primitive types invokes the 6 argument version.  This appears to be because there is no 6 argument version of DualPivotQuickSort.sort(byte[], ...). Is there a particular reason for this?
