Support for Jetty 11 (original) (raw)

Please describe the feature request.
Provide implementation for Jetty 11 users. Due to several big changes, modules written for Jetty 9 are incompatible with Jetty 11 (mostly because of Jakarta EE 9) and it includes the current impl:

• https://github.com/micrometer-metrics/micrometer/tree/main/micrometer-core/src/test/java/io/micrometer/core/instrument/binder/jetty

Rationale

We're migrating to Jetty 11 from Jetty 9 that is based on top of Jakarta EE 9.
Unfortunately micrometer currently supports only 9 and it kinda makes it impossible to operate on that module in our case.
Because we're developing an open-source library, not a private product, it will mostly affect Micrometer's users that would like to use it in further releases of Javalin framework.

Additional context
Should be probably provided as a new implementation as there are still Jetty 9 users that don't want to migrate.
