The resolver is indeed null. It is set to null upon recycling the
pipeline after the first, successful request, and not reinitialised.
This came up already several times on this lisst, without conclusion
so far.
I suspect Saxon produces unexpected code for sitemap_xmap.java.
Xalan is a bit sloppy sometimes when it comes to variable scopes,
perhaps there is a bug in sitemap.xsl. There is also the possibility
of a Saxon bug. I'll try to compare the sitemap javas generated by
Saxon and Xalan tomorrow.
