This build correctly used Java 9. But it did not run successfully. I filed https://issues.apache.org/jira/browse/DERBY-6976 to track this, with the following description: 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] at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) [junit] at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) [junit] at java.base/java.lang.reflect.Method.invoke(Method.java:564) [junit] at java.instrument/sun.instrument.InstrumentationImpl.loadClassAndStartAgent(InstrumentationImpl.java:500) [junit] at java.instrument/sun.instrument.InstrumentationImpl.loadClassAndCallPremain(InstrumentationImpl.java:512) [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: https://groups.google.com/forum/#!msg/jacoco/Zf0Cwj13G2g/wpyrYAEECAAJ 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: # The files here are supposed to be updated automatically twice a month.
