[jboss-jira] [JBoss JIRA] (WFLY-12446) Memory leak in StatelessSessionComponent

[Brian Stansberry (Jira)]

    [ https://issues.jboss.org/browse/WFLY-12446?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13776510#comment-13776510 ] 

Brian Stansberry commented on WFLY-12446:
-----------------------------------------

Note that that duplicate discard call problem would have the effect of slowly increasing the max size of the pool. It doesn't leak 'bad' beans into the pool though. So I believe the size of the queue would be limited to the max # of concurrent requests, so not a never ending leak. So perhaps that is not the cause of the reported problem.

> 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>".
