[Jaikiran Pai (Jira)]

    [ https://issues.jboss.org/browse/WFLY-12446?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13787613#comment-13787613 ] 

Jaikiran Pai commented on WFLY-12446:
-------------------------------------

Thank you [~manovotn] for these details. This indeed makes sense now. The only surprising part to me (as someone who isn't familiar with CDI spec) is that using the same {{Iterable}} (which is the {{Instance}}) multiple times, creates new instances of the underlying bean returned by that Iterable/Instance.

> When running the attached reproducer application and doing a memory analysis afterwards, it looks like a memory leak, e. g.
> {code}
> One instance of "org.jboss.as.ejb3.component.stateless.StatelessSessionComponent" loaded by "org.jboss.modules.ModuleClassLoader @ 0x5e0fbc2e0" occupies 936,593,520 (96.13%) bytes. The memory is accumulated in one instance of "java.util.concurrent.ConcurrentLinkedQueue$Node" loaded by "<system class loader>".
