[jboss-jira] [JBoss JIRA] (WFLY-1097) relax the requirement for having EJB bean class no-arg constructor

relax the requirement for having EJB bean class no-arg constructor ------------------------------------------------------------------ Key: WFLY-1097 URL: https://issues.jboss.org/browse/WFLY-1097 Project: WildFly Issue Type: Feature Request Security Level: Public(Everyone can see) Components: EE Reporter: Cheng Fang Assignee: Stuart Douglas Currently AS7 requires all EJB bean class to have a public no-arg constructor, even when cdi is enabled and there is a @Inject constructor. The deployment of EJB with no default constructor will fail validation. I understand this is a EJB spec requirement, but I guess it's more of legacy from pre-CDI days. I'm wondering if we can relax it, to support EJB bean classes with only @Inject constructor and no default constructor. This is currently supported in GlassFish/RI.
