Maven annotation processing fails with JDK9-ea+138

[Christian Beikov]

Thanks, but I am using the maven-processor-plugin. Nevertheless, I added 
the flags to the plugin since it also allows to add compiler arguments, 
but I get this exception:

java.lang.IllegalArgumentException: invalid flag: -J--add-modules
