When I tried your previous suggestion it didn't work with the same exception. The only way to workaround that was to override GenericAnnotationDeployer output(). Also, when I disabled my custom deployer entirely, I was still able to get AnnotationEnviroment during REAL phase. That's why I think there is another deployer somewhere that attaches AE to deployment unit and that is what causing the conflict.
