Hi Bob, I don't know enough about JSP and how it works with Java 9 (or any Java for that matter), but from a quick google, and some NetBeans knowledge, I believe it doesn't work because the version of Jetty in the 8.2 Java EE plugins was from before java 9 was released (NetBeans 8.2 - 03/10/16 and Java 9 - 27/07/17).
You might want to raise a JIRA ticket[1] against NetBeans, to help ensure Java 9 support when Java EE is enabled in Apache NetBeans.
