Hi,
On the palliative side (i.e. not actually fixing, but at least making life
a bit easier), we might consider a naming scheme for the downloadable that
includes that supported java version, e.g. xwiki-10.3-java8.zip (though
this might also lead users to thinking that the java 8 runtime is
included... which might not be that bad of an idea, if we think about it...
at least for the zip version that is for demo purposes, which already
contains the web server, the database, but still expects the user to
understand and install the correct Java runtime, which makes no sense.)
So, yeah... TL;DR: add the java8 runtime to the .zip package and make life
easier for everyone. Optionally (though not sure if needed anymore, if we
bundle it), include it in the .zip file name.
Of course, the production install, if done manually (i.e. not through
.deb/.rpm packages), expects that the user reads the documentation.
Thanks,
Eduard

with Java
9.
AdminGuide/Installation/
and especially:
AdminGuide/Installation/#HHardwareandSoftwarerequirements
for
reverse order comparator!
with Java
10. Apparently this is fixed in recent version of JBoss
Marshalling: https://issues.jboss.org/browse/JBMAR-216. We probably just
need to wait for JBoss Infinispan to release a new version that uses JBoss
Marshalling 2.1.0.Final.

an app is supposed to be installed by just 'smart' users, not
experts.
If you choose the easy installation methods we propose then it’s easy
and you have
nothing to do.
Which distribution did you choose and use?

Java 10
Xwiki 10.3
tomcat.
If it is not compatible whith this java. It should not install.
It’s just not been tested with Java 10 yet. It’s not even fully working
Note that it’s hard to check for the java version for all the
distributions since
XWiki is a webapp and the XWiki WAR can just be dropped
in a servlet container and thus we don’t have a startup script and a place
where we can put a check. All we could do is have a Servlet Listener that
would emit a big stack trace (like the one you got) and that would say at
the innermost level that XWiki requires Java <= 8. But even that wouldn’t
be good since it would prevent testing in Java 9+. We want feedback from
users about what works/what doesn’t work so improve support for Java 9 and
10.
If it is compatible with only one version of
java, which one?
You need to read the installation page ;)

What this says is that JBoss Infinispan (which we use) is not compatible
What would be awesome would be for you to report the problem of using
XWiki with
Java 10 on https://jira.xwiki.org so that we can have an issue
for it and work to make it work.
Note that I’m replying to this message to help you out but it’s not the
right
place to post a question and get help normally. For that we have a
user forum at https://forum.xwiki.org/.
I’m sorry you had some issues. OTOH you’re looking for trouble by trying
with Java
10. There are very few (if any!) java app that currently work
with Java 9 and 10. You’d be much better off using Java 8. On the positive
side, if you raise the issue on https://jira.xwiki.org, then you will
transform your negative experience into a positive one, by contributing to
the development of XWiki and helping out future users.
Thanks
