PerThread is a scope that operates like jakarta.inject.Singleton scope, except on a per-thread basis. The lifecycle of the service is determined by the thread it is on. On a single thread only one of the service will be created, but a new service will be created for each thread.

The PerThread scope is not automatically handled by a new ServiceLocator. In order to enable the PerThread scope the user can either add an implementation of Context which handles it or it can use the org.glassfish.hk2.utilities.ServiceLocatorUtilities#enablePerThreadScope method.
