Kevan Miller resolved GERONIMO-5200.
------------------------------------
Resolution: Fixed
Should be fixed. Now using ConcurrentHashMap, instead of HashSet.
> high cpu load, probably result of concurrent access of resourcesNotFound in
> MultiParentClassLoader

>
> Sometimes during the use of our webapplication the cpu of our server has
> extereme high load caused by geronimo which stays high forever untillI stop
> geronimo. I have created a thread dump when the cpu load is high (attached to
> this jira). Suspicious in this thread dump are multiple thread in the
> containsKey.
> As not all the access of the resourcesNotFOund map is not synchronized this
> could be the cause of the problem as this might result in a infinite loop
> when the contains method is called during a map resize.
