How to run Integration Tests with JDK 9
If you running your Maven installation with a different JDK than JDK 9 you have give the JDK 9 path via the command line:
mvn clean verify -Prun-its -Dinvoker.javaHome=JDK9JAVAHOME
The reason behind this is simply cause Maven JMod Plugin will call
of the JDK which is needed to be found. Otherwise none of the
integration tests can work.
