Note that we already have a `jetty-version` property defined earlier in the POM, which is used in Jersey tests. We clearly need to consolidate these two. My suggestion:

1. rename `jetty-version` to `jetty.plugin.version` (and make sure it is renamed in all POMs)
2. move your new `jetty.version` property up to the `jetty.plugin.version` (to respect the alphabetical property ordering)
