> Bundle uninstall only removes the BundleRevision from the runtime if it is no longer in use. The classloader associated with an uninstalled bundle that is still in use remains active.
> Approach #1 -  "in use" semantic specific to Bundle deployments
> An undeploy management operation undeploys the bundle revision but holds in the MODULE phase when the revision is still in use
> This is similar to deferred MODULE phase for deploy operation
> in use is not respected for non-osgi deployments and hence breaks bundle deployments that depend on them
> Approach #2 -  "in use" semantic applies to all deployment types
> Undeploy will only destroy the Module service if the Module is not in use by another deployment
> When Module usage drops to zero, undeploy continues and removes the deployment from management 
> This approach would map cleanly - there is no cascading destroy effect. i.e. when you undeploy a jar that a webapp depends on
> Services provided by the undeployed deployment would always go down, only classloader destruction is deferred
