Running project with Jetty 9.4.8 (Java 11)

Question

I'm trying to update my project to Java 11 - OpenJDK_11.0.2 (currently on Java 8). I am using runjettyrun with Jetty version 9.4.8.v20171121.

I can run the project without any issues on Java 8, but if I switch to Java 11, I'll get the following error message:

Answer 1

You must upgrade your version of Jetty.

9.4.9 was the first version to support Java 9.

Error scanning entry "module-info.class" when starting Jetty server

9.4.13 was the first version to support Java 11.

You want to be on 9.4.40, as versions below 9.4.39 are vulnerable in different ways.
