This build correctly used Java 9.

But it did not run successfully. The output said things like:

[java] Java Result: 134
[junit] Exception in thread "main" java.lang.reflect.InvocationTargetException
[junit] at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

[junit] Caused by: java.lang.RuntimeException: Class java/util/UUID could not be instrumented.

Here, I see that to support Java 9, we need JaCoCo 0.7.8:

But it looks like the Jenkins job is using 0.7.6:

++ cat jacocoversion.txt
+ echo 'JaCoCo version: 0.7.6.201602180812'
JaCoCo version: 0.7.6.201602180812

Rick, this one you probably have to track as a separate issue in JIRA; I don't think I can control the JaCoCo version by just changing a Jenkins configuration. Below is what we do in our build, but obviously it didn't automatically move from 0.7.6 to 0.7.8:

1. The files here are supposed to be updated automatically twice a month.
