             Summary: Cloning org.jboss.invocation.InterceptorContext leaks memory
                 Key: WFLY-4187
                 URL: https://issues.jboss.org/browse/WFLY-4187
             Project: WildFly
          Issue Type: Bug
    Affects Versions: 8.1.0.Final
            Reporter: Jeroen Wielandt
            Assignee: Jason Greene


The clone function uses sublist  to set the new list of interceptors. 

public InterceptorContext clone() {
     ....
        clone.setInterceptors(interceptors.subList(next, interceptors.size()));
        return clone;
    }

This will keep a reference to the original list around. So the original list will never be released. Chaining clone multiple times will eventually cause an out of memory because each sublist grows slightly.
