Major Description
Codegen-Plugin failed when :
- maven is executed on jdk9+ (ex : JAVA_HOME on a JDK 11)
- JDK 8 is asked through toolchain plugin
Sample of execution result :

The error seems to come from the additionalJvmArgs for java 9 (--add-exports=..., --add-opens=...) : the command line manually executed failled with these args but succeed whithout). It seems that AbstractCodegenMojo#execute() doesn't test the right JDK to detect if the java 9 additionalJvmArgs should be add : the test is currently on the JDK used by maven instead of the one that will be run by Codegen-Plugin.
