So by default you get none...

Any ideas why no exceptions are being caught?

Another advantage of exceptions is that they do not have to be caught or detected in the place they occur; any code in the thread's call stack can handle a thrown exception.

Are you staing that the exception can only be caught in the function that generates it?

private int MyMethod(){<br />
  throw new EncodingException("this is encoding exception");  <br />
}<br />
int Eaten = 0;<br />
try<br />
{<br />
  Eaten = MyMethod();<br />
}

You should copy the permalink from the threads..

Can you share us more about this bug that you just found?
