Subject [jira] [Created] (CAY-1776) OutOfMemory during lifecycle events

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

             Summary: OutOfMemory during lifecycle events
                 Key: CAY-1776
                 URL: https://issues.apache.org/jira/browse/CAY-1776
             Project: Cayenne
          Issue Type: Improvement
          Components: Lifecycle Extensions
    Affects Versions: 3.1B1, 3.0.2
         Environment: Linux x64, Mac OS X Lion
            Reporter: Nils Verheyen
            Priority: Minor


Inside EventManager.java in Cayenne 3.0.2 and DefaultEventManager in Cayenne 3.1 there is
the inner class Dispatch with the following code:

synchronized (eventQueue) {
                    eventQueue.add(new InvocationDispatch(
                            eventArgument,
                            subject,
                            invocation));
                    eventQueue.notifyAll();
                }

Inside my code a event listener is added once, but inside the eventQueue multiple InvocationDispatch
objects are created and never thrown away. When persisting thousands of objects the eventQueue
is filled up leading to OutOfMemory exceptions.

Regards,
Nils
