-----------------------------------
> Potential memory leak in AsyncDeliveryTask
> ------------------------------------------
>
> Key: FELIX-4663
> URL: https://issues.apache.org/jira/browse/FELIX-4663
> Project: Felix
> Issue Type: Bug
> Components: Event Admin
> Affects Versions: eventadmin-1.3.2
> Reporter: Hartmut Lang
> Assignee: Carsten Ziegeler
> Fix For: eventadmin-1.4.4
>
>
> EventAdmin 1.3.2 can create an OutOfMemory condition caused by not delivered
> async events.
> The problem can occur if an interrupted thread issues an async event (e.g.
> log-event).
> In EventAdmin 1.3.2 the async-delivery uses DefaultThreadPool based on
> PooledExecutor.
> If the already interrupted thread enters the execute-method in PooledExecutor
> an InterruptedException is thrown before the TaskExecutor was added to the
> Thread-Pool.
> This Exception is catched(not handled, only logged) in the DefaultThreadPool.
> As a result the TaskExecuter was not scheduled in the ThreadPool but is still
> part of the m_running_threads.
> All new events are added to the pool of the TaskExecuter, adding in a
> increasing LinkedList. The TaskExecutor is never started again. Memory is
> leaking.
> Seems that 1.4.x is not vulnerable related to interrupted threads. But the
> same catch-and-not-handle block is used in 1.4.x.
