This problem seems to have gone away with an update to the latest CVS (July
9th) version. The XSP processor rejected the page in question (some
<xsp:logic> and <xsp:expr> embedding issues), and after modifying it and
running the app, everything ran fine.
Whether this was something to do with the XSP problems mentioned above
(which for some reason compiled with last week's CVS), or to do with some
other changes - to Xalan, for e.g. - I don't know.
