Hi Claude,

I set up a manually run job on Jenkins to help with this:

https://builds.apache.org/job/Jena_Development_JDK9/

but it runs immediately into plugin problems.

What upgrades did you disable and which upgrade to get anything to minimally compile?

I was trying to get a PR for the java9 changes  but am having significant
problems running java at all.

There were very few changes made for Java9 (only 1 test I thing) and
several plugins that did not work.  I think it would be faster to set up a
bigger development box to perform the java 9 builds and fixes.

Because of the problems, I am going to drop  the branch and may start over
again in the future.

Claude - could this be turned into a PR so we view the changes?

And in other news, the modules vote was lost: 10 for, 13 against.

What that means for Java9 timescale is anyone's guess.

I have created a repository with the java9 branch in it.  I have not
merged
in the last big batch of changes.  but take a look.  I got it to compile
and run the tests however, the site packaging did not work.  I will be
looking at that shortly.  I also removed (commented out)
cobertura-maven-plugin
and
findbugs-maven-plugin

from the parent.pom.

My strategy has been to comment out anything that is not core to the
compile/test/package sequence with a goal to revisit those when the basic
build functionality works.

Repository is at  https://github.com/Claudenw/jena

While at FOSDEM I spoke with one of the developers on Lucene.  He
indicted
that there is a new version of the Maven Compiler plugin that works with
Java 9.  He also had some insight into Memory Mapped files and indicated
that there was a big change coming in Java 10 around this.  I'm not
certain
I understood exactly what the change was but I thought Andy and the
other
TDB folks might want to keep and eye out for any announcements in this
area.

I will be looking at the Java 9 compiler stuff this weekend.

Thanks for the new news - I hadn't spotted anything about mmap files in
Java 10 ... mainly because of not looking yet.

Hopefully value types from Project Valhalla will make it.
