[wildfly-dev] Seeing NPE in org.jboss.as.weld.ejb.StatefulSessionObjectReferenceImpl.isRemoved() during NoSQL testing, how to fix?

[James Perkins]

I think you need to look at why the cache is null. In
the org.jboss.as.ejb3.component.stateful.StatefulSessionComponent it's only
null if the start of the component hasn't been invoked or the done method
was invoked.
