Keith Wall updated QPID-6495:
-----------------------------
Status: Reviewable (was: In Progress)
> Ensure that closing a 0-10 connection from management releases the protocol
> layer's session resources too
> ---------------------------------------------------------------------------------------------------------
>
> Key: QPID-6495
> URL: https://issues.apache.org/jira/browse/QPID-6495
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Reporter: Keith Wall
> Assignee: Keith Wall
> Fix For: 6.0 [Java]
>
>
> On closing a 0-10 connection from management (or Broker shutdown) currently
> consumers are closed, but the protocol layer's session resources remain even
> after the connection itself is closed (ServerConnection#closeAsync)
> The work of QPID-6450 exposed this as a problem. It introduced a VHN scoped
> task executor which is closed as the VHN is closed. In the current
> arrangement this means that it is the Port that attempts to release the
> session's resources, leading to a task executor as the session tries to
> schedule the destruction of its model object on the now closed task executor.
