ArrayIndexOutOfBoundsException when SimpleResourceManager.getListeners()
performs new LinkedList(_listeners);
-------------------------------------------------------------------------------------------------------------
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: Dan Jemiolo
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()
