/**
* A Service is a group of one or more Connectors that share a single
* Container to process their incoming requests. This arrangement allows, for example, a non-SSL and
* SSL connector to share the same population of web apps.
*
* A given JVM can contain any number of Service instances; however, they are completely independent of each other and
* share only the basic JVM facilities and classes on the system class path.
