Josef Puff commented on OWB-1123:
---------------------------------
I've the maybe the same issue.
In my case I have two different Windows Server 2008 R2 with JDK 1.8.0_XX.
On both there is running a Tomcat 8.0.30 with the following server.xml
configuration:
{code:xml}
<?xml version='1.0' encoding='utf-8'?>

My test scenario is following:
- Startup both tomcats
- Login into my application
- Trigger one Function
- STOP one Tomcat (this one, which I'm currently be)
- Check if my Loadbalancer work fine (which works fine)
- Try any request in my application
- Exception in catalina-log from currently running tomcat:

I currently using OWB 1.6.2.
My session database which I use for session replication is couchbase in there
the sessionId's are definitely persisted.

> 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.
