> Key: JENA-1060
> URL: https://issues.apache.org/jira/browse/JENA-1060
> Project: Apache Jena
> Issue Type: Bug
> Components: ARQ
> Affects Versions: Jena 3.0.0
> Reporter: Andy Seaborne
> Assignee: Andy Seaborne
> Priority: Minor
> Fix For: Jena 3.0.1
>
>
> The {{AlarmClock}} code does not cancel alarms properly (it hides and drops
> the {{ScheduledFuture}} needed to cancel an alarm).
> The query timeout code is not exposed to this issue because it has to be
> defensive about a timeout going off unexpectedly anyway (it can't yield the
> first result and reset timeout1 to timeout2 as a single compound, atomic
> action). Similarly, timeouts going off on finished queries have to be
> tolerated.
> The net effect on ARQ is a small build up of outstanding alarms which will
> eventually go away.
