> This was due to the fact that the {{ModuleLifecycle}} from the several modules in the server are sometimes simply ignored.
> The cause is a {{WeakReference<ClassLoader>}} present in {{org.infinispan.configuration.global.GlobalConfiguration}} that sometimes is {{null}} and when the GlobalConfigurationRegistry is started, the Classloader used will default to {{Thread.currentThread().getContextClassLoader()}} that cannot detect the Lifecycle implementations
