Hans Schuell commented on OLINGO-761:
-------------------------------------
I have the same issue under JBoss WildFly Full 9.0.1.Final
When I simply add the following dependency to my pom.xml
<dependency>
<groupId>org.apache.olingo</groupId>
<artifactId>olingo-odata2-core</artifactId>
<version>2.0.5</version>
</dependency>
and compile it, my project doesn't start anymore and the exception is:
Caused by: org.jboss.weld.exceptions.UnproxyableResolutionException:
WELD-001437: Normal scoped bean class
org.apache.olingo.odata2.core.rest.app.ODataApplication$MyProvider is not
proxyable because the type is final or it contains a final method class
org.apache.olingo.odata2.core.rest.app.ODataApplication$MyProvider - <unknown
javax.enterprise.inject.spi.Bean instance>.

I have downloaded the sources now, simply removed the "final" keyword from
public static final class MyProvider implements MessageBodyWriter<String> {
and used "mvn deploy" and THE ERROR IS GONE and when I used it, it is working.
My best guess is that this is an issue with JBoss's implementation, because I
have used olingo-odata2-core before within IBM WebSphere and it worked there.
But the question is "Why must the class be final"?

> I am trying to deploy a web application into WildFly 8.2.0 along with a
> service REST written with JAX-RS,there are just a couple of resources and a
> class extending Application annotated with @ApplicationScoped.
> The application has even a module OData based on Olingo OData 2, version
> 2.0.2.
> During the deployment I get this exception
> {code:borderStyle=solid}

> According to the documentation more or less all the injected beans are
> proxies, the final modifier prevent the subclass to be created.
> Have you already got experience like that?
> Thanks for the attention.
