Jozef Hartinger resolved WELD-920.
----------------------------------
Assignee: Jozef Hartinger
Fix Version/s: (was: 2.0.0.Alpha3)
Resolution: Rejected
Rejecting as this behavior is expected. An optimization has been made as part
of WELD-1076 so that only dependencies that define a @PreDestroy callback are
kept within CreationalContext. A new issue will be filed provided an explicit
destruction mechanism is introduced in CDI 1.1
> Memory leak through the creational context of an @AppScoped bean when
> injecting Instance<>
> ------------------------------------------------------------------------------------------
>
> Key: WELD-920
> URL: https://issues.jboss.org/browse/WELD-920
> Project: Weld
> Issue Type: Bug
> Components: Scopes & Contexts
> Affects Versions: 1.1.0.CR3, 1.1.1.Final
> Reporter: Adam Warski
> Assignee: Jozef Hartinger
> Attachments: leak-test-1.war, leak-test.tar.gz
>
>
> Given a simple dependent-scoped bean: public class InstanceBean {}, and an
> application-scoped bean (see below) to which an instance of the
> dependent-scoped bean is injected, each time the get() method is called on
> the instance, even though it's not used, a reference to it stays in the
> creational context of the application scoped bean
> (http://screencast.com/t/XqjQ1GB7Wv3). That way after several requests, where
> each one calls the method, more and more memory is leaked
> (http://screencast.com/t/s1VBx49i).
> Attached is a simple web application demonstrating this. To reproduce, deploy
> to AS6, click the "leak" button several times, and analyze the heap dump e.g.
> in JProfiler.
> @ApplicationScoped
> @Named("test")
> public class AppScopedBean {
> private Instance<InstanceBean> instanceBeanInstance;
> @Inject
> public AppScopedBean(Instance<InstanceBean> instanceBeanInstance) {
> this.instanceBeanInstance = instanceBeanInstance;
> }
> public AppScopedBean() {
> }
> public void leakOneInstance() {
> System.out.println("Leaked!");
> instanceBeanInstance.get();
> }
> }
