NPE in org.jboss.webbeans.ejb.SessionBeanInterceptor @PostConstruct
-------------------------------------------------------------------

                 Key: WBRI-329
                 URL: https://jira.jboss.org/jira/browse/WBRI-329
             Project: Web Beans
          Issue Type: Bug
          Components: Enterprise Beans, Glassfish integration
         Environment: 1.0.0.PREVIEW2.SP2 in 7/30/09 GlassFish V3 workspace
            Reporter: Ken Saks


SessionBeanInterceptor @PostConstruct is throwing an NPE when the ejb container creates an instance of any session bean component type.   The trace below is for a Singleton.   These are all cases where there is no 299-specific interaction that causes the bean instance creation.   It's just the ejb container creating the instance through some other path , e.g. to eagerly instantiate the Singleton during application startup or to resolve a direct JNDI lookup() from some application code.   I haven't tried a stateful session bean creation via 299-apis or injection yet.  

SessionBeanInterceptor.initBean() first calls  (EnterpriseBean<Object>) EnterpriseBeanProxyMethodHandler.getEnterpriseBean(), which returns null. 
 It then calls (EnterpriseBean<Object>) CurrentManager.rootManager().getNewEnterpriseBeanMap().get(beanClass), which also returns null.   That leads to the NPE on the line "this.beanId = this.bean.getId();"
