QPID-7033: [Java Broker] Change IO tickers use scheduled time when considering
if it is time to 'tick'
> [Java Broker] Busy IO thread pools may cause client connections to be
> unfairly closed
> -------------------------------------------------------------------------------------

> Key: QPID-7033
> URL: https://issues.apache.org/jira/browse/QPID-7033
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: qpid-java-6.0, qpid-java-6.0.1
> Reporter: Keith Wall
> Fix For: qpid-java-6.1
>
> Attachments: 0001-QPID-7033-WIP-fix-ticker-unfairness.patch
>
>
> The Broker installs connection tickers to guard against a new connection that
> sends no bytes or sends bytes too slowly. If the ticker expires, the
> connection is closed with a {{CON-1003 : Closed due to inactivity}} message.
> However, currently a side effect of the Selector Thread's algorithm will mean
> that a connection that whilst ready for read but cannot be scheduled on an IO
> Pool sufficiently quickly enough will also be closed. This is unfair.
> This problem will mean that establishing connections to a busy broker may be
> unreliable. Also a retry effect on the client may exacerbate the situation.
