[jira] [Created] (DIRMINA-1081) Increasing number of ConcurrentLinkedQueue$Node objects

Alexander Buechel created DIRMINA-1081:
------------------------------------------

             Summary: Increasing number of ConcurrentLinkedQueue$Node objects
                 Key: DIRMINA-1081
                 URL: https://issues.apache.org/jira/browse/DIRMINA-1081
             Project: MINA
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.0.16, 2.0.17
            Reporter: Alexander Buechel
         Attachments: linkedqueuenodes.png, recorded live allocations.png

In a few issues i read, that some users detect a hugh number of ConcurrentLinkedQueue$Node objects, which are actually not collected by GC. I dont know if this behaviour is still an open bug, so i opened this new issue.

Attached are two screenshot made by JProfiler. It seems, that the broadcast method references these objects and does not deallocate them.

In my point of view this behaviour was getting better by using version 2.0.17 instead of 2.0.16, but this behaviour still exists.
