Seems the majority of checks were commented out in this commit: - https://github.com/apache/tomee/commit/6bbf5ce32d5a408bde13eefe393c6b1f3381a48d#diff-f6aa0817f9f5b87a8bae7a33578bc10f
Any particular reason? The idea of those checks is to enforce constraints such as the singleton container should be independent and not have dependencies on the stateless container, etc. Making it possible for people to run server with just some containers (say singletons) and not others (MDBs or CMP for example) -David
