Hi Duncan,
could be that your problem is very rarely seen.
I would suggest fo file is as bug in bugzilla.
And please be patient.
Also consider looking into the sources for the DefaultServlet, if you need the
fix very urgently. Maybe you find the bug and could correct it by yourself.
In any case you will understand the problem better and could write a even
better bug report. (Which improves your chances of being heard)
Sorry I cannot test by myself, it's too far off my scope.
Another tip: please give a real-life use case where your bug shows up. This
gives the report more relevance. Also consider testing with/without the
native apr library.
