If _Jetty_ is not on the classpath of an Apache Geode (client or peer) cache application, then Geode will throw an Exception on shutdown:

Ironically, _Jetty_ has NO significance on the client, in a {{ClientCache}} application.
Even when the application embeds a peer {{Cache}}, the server still might not require _Jetty_.
Jetty is only used to enable the embedded HTTP service in a GemFire server-side node (e.g. Locator/Manager or Server).
In the Manager, the embedded HTTP service implemented with _Jetty_ is used to host the Management (Admin) REST API and Pulse.
In a Server, the embedded HTTP service implemented with _Jetty_ is used to host the Developer REST API.
_Jetty_ should only be required when a server-side node (i.e. Locator/Manager or Server) is hosting the Developer/Management REST API or Pulse.
Please consider this change!
