# Instrumentation for Jetty request handlers

Jetty support is divided into the following sub-modules:
- `jetty-common:javaagent` contains common type instrumentation and advice helper classes used by
  the `javaagent` modules of all supported Jetty versions
- `jetty-8.0:javaagent` applies Jetty request handler instrumentation for versions `[8, 11)`
- `jetty-11.0:javaagent` applies Jetty request handler instrumentation for versions `[11,)`

Instrumentations in `jetty-8.0` and `jetty-11.0` are mutually exclusive, this is guaranteed by the
instrumentation requiring parameters with types from packages `javax.servlet` or `jakarta.servlet`
respectively.
