> Key: QPID-6171
> URL: https://issues.apache.org/jira/browse/QPID-6171
> Project: Qpid
> Issue Type: Bug
> Components: Java Common
> Reporter: Rob Godfrey
> Assignee: Rob Godfrey
> Fix For: 0.31
>
>
> the collection returned by getChannels() may be modified by other threads,
> leading to unsafe iteration throwing ConcurrentModificationException.
> The returned object should instead be a copy of the data and the underlying
> map should use a thread safe implementation to allow for the safe copying of
> the values() collection while another thread may be modifying the map.
