> Replace WeakIdentityCollection in StateChangeDispacher
> ------------------------------------------------------
>
> Key: JCR-618
> URL: http://issues.apache.org/jira/browse/JCR-618
> Project: Jackrabbit
> Issue Type: Improvement
> Affects Versions: 1.1
> Reporter: Tobias Bocanegra
> Assigned To: Tobias Bocanegra
> Fix For: 1.2
>
>
> As a leftover from event refactoring, the listeners in the
> StateChangeDispatcher are still
> managed by a WeakIdentityCollection and for every notify event, it's
> synchronized and copied
> into an array. this is very expensive and unnecessary.
> since the addition and removal of listeners is now controlled, and listeners
> can't just disappear,
> it possible to use a normal collection.
> Suggest to replace the WeakIdentityCollection by a
> 'EDU.oswego.cs.dl.util.concurrent.CopyOnWriteArrayList' that allows read
> access (and iteration)
> without synchronization.
