exception with no stack trace - how?

Question

We have a service which will log unhandled exceptions at the app domain level (via Log4net).

We logged:

2014-01-28 16:49:19,636 ERROR [49] Fe

Answer 1

If you're receiving an exception but no corresponding stack trace then at some point an exception handler is probably evaluating the exception and re-throwing it incorrectly. For example, if you're doing a throw ex; you'll eat the stack trace that led to that point. To preserve the existing call stack you want to simply throw; Throwing exceptions best practices

Note that the C# way is the opposite of the convention for the Java language, where you are supposed to throw ex; Java reference: Best Practice: Catching and re-throwing Java Exceptions
