-----------------------------------------

Hi Michael

The branch on the svn will be rollback this week (it belongs to a release 
procedure done in december that does not passed), so you have to check trunk. 
or 2.0.x branch. A release of 2.0.12/2.1.6 will take some time while I include 
some cool performance enhancements, so stay tuned.

best regards,

Leonardo

> 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
