Bauke Scholtz commented on OWB-1123:
------------------------------------
When digging further, the root cause appears to be the below which got logged
when TomEE was shutdown instead of restarted. When TomEE was restarted, this
warning goes unnoticed because the IDE clears out the entire console.
{code}
WARNING: Cannot serialize session attribute openWebBeansSessionContext for
session 34F40C623600849F43AD2153F2EB75D8
java.io.NotSerializableException: org.apache.webbeans.container.BeanManagerImpl
at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1184)
{code}
When above is logged on shutdown, then the startup will consistently throw NPE
on createNormalScopeProxy. I will this week try to create a reproducer.
> NPE at NormalScopeProxyFactory.createNormalScopeProxy during deserialization

> Key: OWB-1123
> URL: https://issues.apache.org/jira/browse/OWB-1123
> Project: OpenWebBeans
> Issue Type: Bug
> Affects Versions: 1.6.2
> Environment: TomEE 7.0.0.M2
> Reporter: Bauke Scholtz
> Assignee: Mark Struberg
>
> Imagine a session scoped bean which has an application scoped bean injected
> as property and it's being referenced in {{readObject()}}.
> {code}
> @SessionScoped
> public class SessionScopedBean {
> @Inject
> private ApplicationScopedBean appBean;
> private void readObject(ObjectInputStream input) throws IOException,
> ClassNotFoundException {
> appBean.doSomething();
> }
> }
> {code}
> 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):
> {code}
> java.lang.NullPointerException
> at
> org.apache.webbeans.proxy.NormalScopeProxyFactory.createNormalScopeProxy(NormalScopeProxyFactory.java:121)
> at
> org.apache.webbeans.intercept.NormalScopedBeanInterceptorHandler.readResolve(NormalScopedBeanInterceptorHandler.java:125)
> {code}
> 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.
