> We have some EJBs in our application which we disable during development by voting against them with a CDI extension.
> When we upgraded from JavaEE6 (OpenEJB 4.7.4) to JavaEE7 (OpenEJB 7.0.2) we encountered NullPointerExceptions in OpenEJBLifecycle:265 (see attached openejb-trace.log).
> Our EJBs look like this:
> {code}
> @javax.ejb.Startup
> @javax.ejb.Singleton
> @Exclude(ifProjectStage = {Development.UnitTest.class})
> public class MySingletonEJB { [...] }
> {code}
> The CDI extension just does some evaluation based on the parameters in {{@Exclude}} and calls {{processAnnotatedType.veto()}} like
> {code}
> vetoBeans(@Observes ProcessAnnotatedType pat) {
>     if ([...]) pat.veto();
> }
> {code}
> I debugged OpenEJBLifecycle a bit and it looks like the beanManager does not "know" the bean (because it got vetoed), but OpenEJB assumes to get a bean reference from it. The NPE happens when calling {{bean.getScope()}}, because {{bean}} is null.
> {code}
> // OpenEJBLifecycle:263-265
> private void starts(final BeanManager beanManager, final Class<?> clazz) {
>     final Bean<?> bean = beanManager.resolve(beanManager.getBeans(clazz));
>     if (!beanManager.isNormalScope(bean.getScope())) {
>         [...]
> {code}
