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();"
