> Key: UIMA-303
> URL: https://issues.apache.org/jira/browse/UIMA-303
> Project: UIMA
> Issue Type: Bug
> Components: Collection Processing
> Reporter: Adam Lally
> Assignee: Marshall Schor
> Priority: Minor
> Fix For: 2.2
>
>
> In the CPM, the method BoundedQueue.dequeue(timeout) is supposed to wait for
> the specified timeout for a CAS to become available. However from a code
> inspection it looks like there are problems with its synchronization. If
> multiple threads are waiting, and one CAS becomes available, then all of the
> threads will wake up, but only one will get the CAS. The others will return
> null prematurely, without having exhausted their timeout.
> Also there may be a problem with chunking enabled and a chunk timeout is
> specified, where the timeout does not actually do anything except log a
> message.
