> When the {{installAtEnd}} configuration parameter is set to {{true}} on a multimodule project with multiple class realms then because a different class loaders creates instances of the {{InstallMojo}} class there will be muliple instances of {{readyProjectsCounter}} and {{installRequests}}.
> However, because the end is determined by {{projectsReady = readyProjectsCounter.incrementAndGet() == reactorProjects.size()}} it will never complete as {{readyProjectsCounter}} will never equal the size {{reactorProjects}} if even one project is executed in another class realm.
> {{maven-deploy-plugin}} partially solved this in MDEPLOY-193 by using {{project.equals(reactorProjects.get(reactorProjects.size() - 1))}} instead.  However, the installation is a little more complex than the deploy as we need to read the used the {{createChecksum}} and {{updateReleaseInfo}} configuration parameters from each installed project - we can't store them ahead of time because of the issue with the class realms, so we need to read the plugin configurations before we can call {{installProject(instalRequest)}}.
