[OWB-1123] NPE at NormalScopeProxyFactory.createNormalScopeProxy during deserialization

• Type: Bug

Description

Imagine a session scoped bean which has an application scoped bean injected as property and it's being referenced in readObject().

@SessionScoped
public class SessionScopedBean {

    @Inject
    private ApplicationScopedBean appBean;

    private void readObject(ObjectInputStream input) throws IOException, ClassNotFoundException {
        appBean.doSomething();
    }
}

OWB 1.6.2 as used in TomEE 7.0.0.M2 throws below exception when TomEE is restarted with session persistence (and above bean is created during that session):

java.lang.NullPointerException
    at org.apache.webbeans.proxy.NormalScopeProxyFactory.createNormalScopeProxy(NormalScopeProxyFactory.java:121)
    at org.apache.webbeans.intercept.NormalScopedBeanInterceptorHandler.readResolve(NormalScopedBeanInterceptorHandler.java:125)

It works fine in all Weld 2.x versions I tested so far (WF8/9/10, PY4 and "plain" Tomcat8+Weld 2.3.0).

Work around would be to use a static method on application scoped bean, but this is not nice.
