@srowen I tried digging a bit deeper into this.
Via 'dependency:list -DincludeParents=true', on master, I do see jetty
dependencies making into the dependencies for thrift server.
Via 'dependency:analyze', in master for thrift server, I see this :
```

```
Which matches what I see in the classpath declarations - that jetty
dependencies are making it into classpath.
I suspect it perhaps has to do with provided scope interacting with test
scope dependencies.
After this PR, 'dependency:list -DincludeParents=true' does not show jetty
as a dependency without the explicit inclusion above.
Given this, I assume adding the explicit dependency is the right thing to
do (it is a transitive depedency anyway currently). In order to preserve
earlier behavior of not including jetty with compile scope, I am explicitly
changing the above to 'provided' scope.
Any thoughts @srowen ?
