The nine lines:

    private static void rangeCheck(int arrayLen, int fromIndex, int toIndex {
         if (fromIndex > toIndex)
              throw new IllegalArgumentException("fromIndex(" + fromIndex +
                   ") > toIndex(" + toIndex+")");
         if (fromIndex < 0) 
              throw new ArrayIndexOutOfBoundsException(fromIndex);
         if (toIndex > arrayLen) 
              throw new ArrayIndexOutOfBoundsException(toIndex);
    }

That spacing around the final + in the third line is horrendous.
