> Key: MUSE-285
> URL: https://issues.apache.org/jira/browse/MUSE-285
> Project: Muse
> Issue Type: Bug
> Components: Core Engine - Resource and Capability APIs
> Affects Versions: 2.2.0
> Environment: any
> Reporter: Eitan Plotnik
> Assignee: Chris Twiner
> Fix For: 2.2.1
>
>
> SimpleResourceManager.getListeners() invokes new LinkedList(_listeners) which in turn calls toArray() on the _listners linked list in the argument.
> The toArray() throws ArrayIndexOutOfBoundsException in case objects were added to _listeners while it's in progress.
> addListener() and removeListener() are synchronized methods. I think so should be getListeners().
> I think getListeners() signature should be modified
> from: protected List getListeners()
> to: protected synchronized List getListeners()
> Stack trace:
> java.lang.ArrayIndexOutOfBoundsException: 1606
