These seam to occur after some time of inactivity, on my test system it happens after about 1 hour but in the live system it can happen already after 5-10 minutes causing the application to fail.

What can be the reason? I saw some suggestion on a similar case that the bean would have an atttribute which isn't Serializable but all my attributes are Serializable as far as I can find.

The problem is caused by
...
at java.lang.Class.newInstance0(Class.java:335)....
...

Try this fix:
All stateful bean's variables should implement serializable object and contain their own default constructor

Hi,
the problem is that my stateful bean does implement Serializable and do have a default constructor. I've also searched all the attributes and they also implements Serializable.

That's why I'm pretty lost on this one...

Ok, maybe I've found it. Look at this:

queue = new PriorityBlockingQueue<QueueItem>(result.size(), new Comparator<QueueItem>() { public int compare(QueueItem o1, QueueItem o2) { // This will cause the queue to be sorted in the inverse natural order // i.e. higher numerical value of priority attribute gives higher priority return -o1.getPriority().compareTo(o2.getPriority()); } });

The stacktrace says the problem is to instanciate
CallHandlerActionBean$1, i.e. an anonymous inner class of CallHandlerActionBean. I had searched for it before but didn't find it until now.

This kind of constructions are quite common in example code but obviously easy to blow a big hole in the foot...
