Upgrade to Jetty 12

[wilkinsona]

Work in progress is available in https://github.com/wilkinsona/spring-boot/tree/jetty-12. Related Jetty issues with 12.0.0.beta2:

• getResourcePaths fails when a META-INF resource has reserved characters in its filename jetty/jetty.project#9972 (inconvenient)
• Creating a Resource for an entry in a nested jar file in Jetty 12 jetty/jetty.project#9973 (blocker)
• URLResource.isDirectory() throws a NullPointerException when created from a jar:file: URL jetty/jetty.project#9984 (blocker)

Hi,

Does the spring-boot-starter for Spring Boot 3 work now with Jetty 12 ?
I understand SP3 doesn't work with Jetty 11, because it's not supporting EE10 (Servlet 6.0)

No, not yet. There are a significant number of breaking API changes in Jetty 12 to which Spring Boot will have to adapt. We hope to support Jetty 12 in Spring Boot 3.2 and Spring Framework 6.1.

Spring Boot 3 works with Jetty 11 but you have to downgrade the Servlet API to 5.0. #33044 contains various ways to do that with both Maven and Gradle.

Is there an active branch with this effort where I can participate in?

[wilkinsona]

Thanks, @joakime. spring-projects/spring-framework#30698 is the next piece in the puzzle. I don't know if there's an active branch for that work.

Jetty 12.0.1 is GA now

[wilkinsona]

Thanks, @lzysuqianqiu. As you can see from the branch that's linked in this issue's description, we are already aware of that.

spring-projects/spring-framework#30698 should land in Framework this week, allowing us to tackle this in 3.2.x.

Is there already a releaseDate for SP 3.2?
