Hi David,
not sure what you mean? Does the Oracle JDK come with another launcher
compared to the OpenJDK?
I've just tried with the latest EA build 170 (which I assume is an
Oracle JDK) and I see exactly the same error:
java -Djava.security.manager -showversion Tricky ""
java version "9-ea"
Java(TM) SE Runtime Environment (build 9-ea+170)
Java HotSpot(TM) Server VM (build 9-ea+170, mixed mode)
Error: A JNI error has occurred, please check your installation and try again

So what do you mean when saying that you don't see it in the Oracle JDK?
