[weld-issues] [JBoss JIRA] (WELD-1016) Weld creates multiple interceptor instances per target instance

Weld creates multiple interceptor instances per target instance --------------------------------------------------------------- Key: WELD-1016 URL: https://issues.jboss.org/browse/WELD-1016 Project: Weld Issue Type: Bug Components: Interceptors and Decorators Affects Versions: 1.1.2.Final Reporter: Jozef Hartinger Assignee: Marko Lukša Fix For: 1.2.0.Beta1, 2.0.0.Alpha2 The CDI spec says: {quote} An interceptor instance is a dependent object of the object it inter-cepts. {quote} The Interceptors spec says: {quote} The lifecycle of an interceptor instance is the same as that of the target class instance with which it is associated. When the target instance is created, a corresponding interceptor instance is created for each associated interceptor class. These interceptor instances are destroyed when the target instance is removed. {quote} and also {quote} An interceptor instance may hold state. {quote} It is clear that at most one instance of an interceptor class should be created for an instance of a CDI bean. However, Weld currently creates an instance per method per target instance. Having a simple intercepted bean: {code:JAVA} @ApplicationScoped @LionBinding public class Lion public Object foo() { return null; } public Object bar() { return null; } } {code} * multiple invocations of a single method (e.g. foo()) are intercepted by the same interceptor instance * when invoking different methods on the same bean instance, every method is intercepted by a different interceptor instance - which is wrong
