See Jetty ContextHandler.java Looks like a bug in jetty, see where on startup the content of the _servletContextListeners is copied to _destroyContextListeners:

https://github.com/eclipse/jetty.project/blob/7b38981d25d14afb4a12ff1f2596756144edf695/jetty-server/src/main/java/org/eclipse/jetty/server/handler/ContextHandler.java#L874-L893

Afterwards, when removeEventListener is invoked:

https://github.com/eclipse/jetty.project/blob/7b38981d25d14afb4a12ff1f2596756144edf695/jetty-server/src/main/java/org/eclipse/jetty/server/handler/ContextHandler.java#L691-L709

We see that while the "_servletContextListeners" is cleared, the copy already made to the "_destroySerletContextListeners" is not removed. This means that the listener is still invoked on shutdown after the client has specified that it should not be.

The _destroyServletContextListeners is private final:

https://github.com/eclipse/jetty.project/blob/7b38981d25d14afb4a12ff1f2596756144edf695/jetty-server/src/main/java/org/eclipse/jetty/server/handler/ContextHandler.java#L209

So we can't remove this listener on shutdown without Jetty intervention.
