-1 for 5.0.16There's a new Xerce 2.6 release, but I still plan to include 2.5 in
tomorrow's tag (which works). 2.6 *apparently* works (without any
noticeable improvements either), but I fear possible schema related
regressions. So not upgrading for this tag is intentional, and I'll
update build.properties right after the tag :)
It works indeed.
I performed a microbenchmark measuring tomcat startup times without validation,
with xerces 2.5 and xerces 2.6.
run1 run2 run3 avg norm1 norm2 norm3
off 17715 17606 17445 17588 1 0,80 0,88
2.5 21771 21841 21845 21819 1,24 1 1,09
2.6 19988 19769 19858 19871 1,12 0,91 1
I have made three runs (columns run1, run2 and run3)
Since startup times measured in ms are of no special interest (they depend on
particular hw/sw platform), columns (norm1, norm2 and norm3) show data normalized
to avg of off, 2.5 and 2.6 respectively.
Row names are self explanatory.
I think that if there are no regressions in xerces 2.6 it is worth switching to
(provided you *do* validate xmls).
Every release of Xerces is dangerous (buggy!), and to quote Rémy: "2.6 *apparently* works" scares me ;-)

Let the discussion begin.
