There are problems with getting the Brooklyn UI to work with the `jetty`
and `cxf` upgrades. The OSGI feature `brooklyn-rest-resources` fails to start,
reporting a `NoClassDefFoundError` for `javax.xml.ws.*`. The suggestion from
the [Karaf Mailing
List](http://karaf.922171.n3.nabble.com/Karaf-4-2-1-JDK-10-provide-jax-ws-td4054044.html),
is to add the OSGI wrapper for the JAXWS API:
`mvn:org.apache.servicemix.specs/org.apache.servicemix.specs.jaxws-api-2.2/2.9.0`
bundle. However, I haven't been able to make this work.
The task of upgrading `jetty` and `cxf` will be deferred for now:
