GWT Code Server Jetty Mismatch

I raised a Spring Boot Jetty issue https://github.com/spring-projects/spring-boot/issues/49220 because I thought there was an issue with Jetty.

Turns out, the GWT Code Server is bringing in an old version of Jetty which breaks Spring Boot.

When I tell Spring Boot to use the version of Jetty it wants, the GWT Code Server then breaks with the error:

Is there a way to allow Spring Boot to use Jetty 12.1.5, but also let the GWT Code Server use Jetty 9.4.58?

(Apologies if this has been asked before, I searched around and couldn't find it)
