Infinite loop when calling ApplicationImpl._handleListenerForAnnotations under
heavy load
-----------------------------------------------------------------------------------------
Key: MYFACES-3442
URL: https://issues.apache.org/jira/browse/MYFACES-3442
Project: MyFaces Core
Issue Type: Bug
Affects Versions: 2.1.3
Reporter: Michael Dietrich
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,
Michael
