jena-elephas and surefire.

jena-elephas-io does not pass its test suite with maven-surefire-plugin 
v2.20 or v2.20.1. The latest version of the plugin is 2.20.1. we have 
been using 2.19.1 until now.

jena-elephas-io uses <parallel>classes</parallel>

This is not specific to Java9 - this is using using java8 to build with 
updated plugins [1] - however, v2.20.1+ is required for Java9 [2]

The first error is:

[INFO] Running 
org.apache.jena.hadoop.rdf.io.output.trig.TriGBlankNodeOutputTests

and then several the same for a total of 12 for TriGBlankNodeOutputTests.

Temporarily, we can specifically set the plugin in 2.19.1 but this is 
masking the problem, not removing it.
