Hi Sherman.
When you say:

produces

Is it possible to have a starting sequence of one or more zero-width matches?
The matcher.find() always increases its "next find start position" at least one
as showed in Matcher.find() impl ("first" starts from -1), so the matcher.find()
should keep going forward, never produce more than one zero-length substring.
OK.
Matcher:
public boolean find() {
int nextSearchIndex = last;
if (nextSearchIndex == first)
nextSearchIndex++;

The webrev has been updated to use your optimized version in splitAsStream().

I still think it would be useful to add a comment at the relevant code location
about zero-width match behaviour.
Thanks Paul!
I added two lines of comment as suggested.
