--- Comment #3 from Michael Osipov <michaelo@FreeBSD.org> ---
Tomcat committer here. I am fairly well acquiant with the libtcnative code =
and
looking at your description (quick scan) it does not make sense since the A=
PR
connector does not use any Java code actually...We need to try to isolate t=
his
outside of Tomcat to get a better understanding. Means:

* Bind a dual-stack socket with plain Java
* Bind a DS socket with APR, e.g.,
https://gist.github.com/michael-o/dfb86df472f62d2b2dff6ef12ee3758e
* Bind a DS socket with Python which is very near to low-level C code

and check with sockstat.

Can you meanwhile provide details:

OS version, etc. Ultimately, I need to understand who's fault this is and w=
hat
we need to fix.
