This page is the best (to my knowledge) comparison we can have. It's updated
because it follows development, but the book only includes official releases
(a new one should be coming soon according to [1]). So it may be out of date,
but I'd say it's better than nothing. As of your request, it makes no sense
that the maintainer of the java page publish his test results. A point does
not make statistics... Also, I do not have always the time (or the will)
to sort out all the test failures. Last time I run the tests, I had
consistently more than 50 errors, all in the same area, so I think it was more
of a problem with my configuration than with the package. And all in all, it
was just 50 out of more than 6,000. So what would be the value of publishing
those tests results?

At least, the referenced page may be used to see whether some failures may be
considered as "known"... I may change the wording to something like `Upstream
runs the tests regularly, so you may want to look at these "test results
(link)". Those results may show which tests can be considered as "expected to
fail", but may differ from yours since they are not run on exactly the same
sources.'

Also I think we have put too much emphasis on tests in the book at a certain
time. It was a waste of time, because tests more often reflect upstream
inability to fix things than something going really wrong. And it is very
unlikely that a particular test show something wrong in a build. Of course,
more that 10-20 % of failures should warn about something possibly going
wrong, but only "possibly". The present editors team is doing much better in
this respect.
