[jira] [Reopened] (MYFACES-3442) Infinite loop when calling
ApplicationImpl._handleListenerForAnnotations under heavy load
[ https://issues.apache.org/jira/browse/MYFACES-3442?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Leonardo Uribe reopened MYFACES-3442:
-------------------------------------
It seems ConcurrentHashMap cannot be used because it is required to support null values. So I changed the solution to use a synchronized block over the map. That should do the trick.

> Hi,
> when doing Load Tests, we recognize that we sometimes got stuck in an infinite loop, when calling the _handleListenerForAnnotations method of the ApplicationImpl class. According to our analysis, this is related to the _classToListenerForMap attribute that is is defined as plain HashMap, so no synchronisation takes place when it is accessed from several threads. Our suggestion would be, to define it as a ConcurrentHashMap instead, because according to our experience, such kind of infinite loops due to concurrency don't occur with ConcurrentHashMaps.
> Kind regards,
