public class ACLSingletonProvider
extends org.jboss.weld.bootstrap.api.SingletonProvider

Singleton provider that uses Application ClassLoader to differentiate between applications. It is different from TCCLSingletonProvider. We can't use TCCLSingletonProvider because thread's context class loader can be different for different modules of a single application (ear). To support Application Scoped beans, Weld needs to be bootstrapped per application as opposed to per module. We rely on the fact that all these module class loaders have a common parent which is per application. We use that parent ApplicationClassLoader to identify the singleton scope.
