Better error message for @ManagedBean annotated Beans that do not have a no-arg constructor ------------------------------------------------------------------------------------------- Key: WELD-733 URL: https://jira.jboss.org/browse/WELD-733 Project: Weld Issue Type: Feature Request Components: Class Beans (Managed and Session) Reporter: Sivakumar Thyagarajan If we have an @ManagedBean annotated class that does not have a no-arg constructor, and is CDI-enabled(for instance has an interceptor binding annotation assigned to one of its methods), Weld proxy creation fails with an InstantiationException(see below) because of the missing no-arg ctor. It would be nice if Weld detects this case better and provides a better error message. I have filed a GlassFish issue (GlassFish issue 14076) for us to fail deployment, but Weld's handling of this issue would help GlassFish and other containers.
