When using Jetty version 10.0.5 and Java 11 with Spring Boot 2.5.6 .. .9 or 2.6.0 still the in #26847 described problem occures.
To reproduce the failure the existing setup description of the #26847 thread should be sufficient. I also created a pom.xml from https://start.spring.io/ and added the jetty 10.0.5 version to the properties tag (and some additional dependencies).
