why is Span#getLength() long?

Hi

Is there a reason Span#getLength() returns a long?
Since start and end are int's, it seems like getLength() should also be
an int.

It is because the length of the span can overflow the range supported by the int type. However, in verifying this, I discovered a bug in the calculation - because the values were not being cast to long beforehand, they were being evaluated as ints and overflowing anyways. Thanks for catching this.
