Hey @Maciej Walkowiak @Tomas Bjerre I’ve opened a couple of draft PRs against the Spring Boot integration: 1. https://github.com/wiremock/wiremock-spring-boot/pull/66 - switch to WireMock Jetty 12 thin JAR instead of the Jetty 11 standalone. 2. https://github.com/wiremock/wiremock-spring-boot/pull/67 - add support for extension factories declared via the annotation (depends on https://github.com/wiremock/wiremock/pull/2909) Would be great to get a sanity check from one/both of you if possible. I guess one concern might be whether the Jetty12 change would have the effect of dropping support for an earlier version of Spring Boot?
