It's exactly as Joe already explained. Whenever we use client proxies in JavaEE
(which is for *all* NormalScoped CDI beans plus all NoInterfaceView EJBs) we
generate a dynamic subclass on the fly ('Contextual Reference') which overloads
all the methods and delegates through to the 'Contextual Instance'
For a native class
public class User {
private String name;
public String getName() { return name; }
public void setName(String name) {this.name=name;}
}
we will create a new class on the fly (see NormalScopedProxyFactory in our
code) which is like:
public class User$$OwbNormalScopeProxy extends User {
private User owbContextualInstanceProvider;
@Override
public String getName() { return owbContextualInstanceProvider.getName();};
@Override
public void setName(String name) {
owbContextualInstanceProvider.setName(name); };
}
And of course this 'Contextual Reference' can only use the default constructor
of the proxied class.
Btw, this is one of the reasons why you should always use @PostConstruct and
not the ct to initialize your beans.
