A summary of what I discussed with Romain on IRC: According to the JavaEE spec only checked Exceptions and RuntimeExceptions which are marked as @ApplicationException must get transfered over @Remote (regardless if this is a real client or even inside the same JVM). For others the Exception gets re-packaged into a javax.ejb.EJBException.
TomEE takes some internal Exceptions and additionally transfers them along to the client. This is mainly as some TCKs are strictly speaking broken as they test for DefinitionException, DeploymentException, OptimisticLockException and other internal exceptions (which are RuntimeExceptions). But this only works as long as there is a cdi and jpa spec API jars are available on the client. Since the TomEE server doesn't know what is on the client it usually wraps Exceptions into a ThrowableArtifact which contains the original Exception (basically manually serialized as byte[]) plus also the String representation. If it is not possible to deserialize the original Exception (because javax.persistence.OptimisticLockException.class is not available on the client) then it falls back to unwrapping to an EJBException plus adding the String information of the original Exception. TomEE did this wrapping only for custom Exceptions so far. But it also needs to provide the same for DefinitionException and DeploymentException as this might contain custom MyVersyOwnOnlyOnServerExtensionException which got thrown by an Extension on the server. And this will get added as Cause to the DeploymentException. So even if we don't serialize a WebBeansDeplyomentException but a spec DeploymentException instead then we still have the problem with all the containing causes which are not available on the client side (and thus will make the app fail with a ClassNotFoundException).
