Following scenario:
{code:java}
public class MyService {
@Inject
private EntityManager em; // injects a WELD proxy
public void test() {
em.unwrap(SessionImplementor.class).getFactory();
}
}
{code}
Calling {{MyService#test}} results in a ClassCastException:
{noformat}
java.lang.ClassCastException: org.jboss.weldx.persistence.EntityManager$470189163$Proxy$_$$_WeldClientProxy cannot be cast to org.hibernate.engine.spi.SessionImplementor
{noformat}
This is becuase the condition at {{org.jboss.weld.bean.proxy.ProxyMethodHandler:103}} causes the method handler returns to return {{self}} instead of {{this}}. The return type of {{EntityManager#unwrap}} is unbounded generic so
{code:java}
thisMethod.getReturnType().isAssignableFrom(self.getClass()))
{code}
always is true.
