afaik this is not explicitly stated in the spec, but I think an EventHandler should expect to be called in parallel. For example, this can happen if two threads send an event with the same topic in parallel. So an event handler implementation should be thread safe. As soon as you make any assumptions like "this only happens with async events" or whatever, you're tying yourself to some characteristics of a specific implementation of the event admin. Therefore just asume that i can happen and you're safe Carsten -- Carsten Ziegeler [email protected] --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
