That's what the new method setTrimText(true) is for.  The idea is:
either you 

 - pass whitespace through unchanged, and turn off newlines and indent

 - or strip it with trimText, and turn on newlines and indent

I'm reluctant to add this property to the constructor, since it's a
slippery slope.  In fact, I'd like to strip all but the default
constructor, but I can see how some find the extra constructors

On reflection, maybe there should be a constructor

XMLOutputter(boolean trimText, boolean newlines, boolean indent)

So you can simply call

new XMLOutputter(false,false,false)

for the first case,

new XMLOutputter(true,true,true)

for the second, and

new XMLOutputter(true,false,false)

for the most compact representation.

Yes, and since the whitespace between the doctype and the first (root)
element is effectively stripped, since there's no place for a text
child of Document (only comments, PIs, and a single element).  I

No, that's not necessary.
