[Jeff Janner] 
I'm not sure the above applies for APR, I've never gotten it to work (at least not on Windows).
It appears that APR defaults to IPV6 if no address is given.  If you look back in this list
for about a year to year & a half, you'll see much discussion on this.  I am not positive
that this has not been addressed yet, as I've resorted to specifying address='' in
all my connectors since I ran into the problem.  Give it a test and see.
I think you are correct however for the JRE-based connectors.
