Avoid blocking access to EntityManagerFactory in DataSourceInitializedPublisher #14061
Description
During our optimization efforts in JPA bootstrapping we stumbled above DataSourceInitializedPublisher.publishEventIfRequired(…) calling EntityManagerFactory.getProperties().
In case of an asynchronously bootstrapped EntityManagerFactory this will cause the initialization to block and prevent the container from continuing to initialize other components. I wonder it there was a way to rather consume the DataSource by inspecting EntityManagerFactoryInfo.getDataSource() as method calls to this interface do not trigger the blocking.
