Thanks for finding that out. Some trickery to get a java8 tools.jar
available might work but would be awfully unstable, needing path names.

Warning - switching build for java9, not just build with java9 for
java8, crashed Eclipse for me in such a way I had to delete the
workspace and rebuild but I had been chopping and changing git branches
and java versions so not entirely fair.

The Hadoop libs, even the latest major release version 3.0.0, are still

Thus, it could be a blocker.

JENA-1475
I've managed to the build working with java9, outputting java8
compatible classes.
PR#350.
https://github.com/apache/jena/pull/350
This is using Apache parent v18 (so not JENA-1474)
but
1/ -Pdev build
Works:
mvn clean install -Pdev
because it sets -Dmaven.javadoc.skip=true
2/Full build, jaavdoc
javadoc fails at jena-core (despite it compiled). The problem is
java.xml.bind - it looks to me like the javadoc is running in "java9"
mode and I haven't found out how to override that.
3/ Full build, no javadoc
mvn clean install -Dmaven.javadoc.skip=true
runs until jena-elephas-common.
