NPE when webBeansContext.getApplicationBoundaryService() in AbstractProxyFactory
Hi,
I'm trying to upgrade tomee support in our server from tomee 1.6.0.3 to
1.7.2. SInce 1.7.2 is not released yet I'm using 1.7.2-SNAPSHOT.
After doing the changes when I deploy an simple CDI app it throws following
exception (I deployed and run the same app with 1.6.0.3 it works fine there)
ERROR {org.apache.catalina.core.StandardWrapperValve} - Allocate exception

After some debugging the both versions I found out that NPE is get thrown
because ApplicationBoundaryService applicationBoundaryService in the
WebBeansContext
is null.
The only possible place that I see where it get initialized is in the
overloaded constructor of the WebBeansContext.
Did I missed setting any configurations?
Can someone guide me on solving this?
Thanks
Best Regards

Hi All,
I'm extremely sorry for the mistake. This should be sent to the
openwebbeans user groups.
Sorry again.

Re: NPE when webBeansContext.getApplicationBoundaryService() in AbstractProxyFactory
Posted by Mark Struberg <st...@yahoo.de>.
well, that should not happen of course ;)
I can give you a quick explanation what the ApplicationBoundaryService is for.
We use it to get the ClassLoader to use for a class we need to proxy.
Say if we create a CDI proxy (Contextual Reference) for a MyCustomCdiBean in your project then we usually take the ClassLoader of this class.
Now imagine you have a producer method:
private @PersistenceUnit(name=„myPu“) EntityManagerFactory emf;
@Produces
@RequestScoped
public EntityManager createEM() {
return emf.createEntityManager();
}
In that case we would take the ClassLoader from EntityManager.class to create the proxy. But that would obviously create a mem leak. Thus we introduced an ‚outer boundary ClassLoader‘ which is the WebAppClassLoader of your webapp. Or in case of an EAR the EAR-ClassLoader. Makes sense?
Do you have a sample application where we can reproduce this bug?
LieGrue,
