Exception serialization problem with remote access

In a statefull sessin bean I redirect a possible Exception like this

catch (Exception e)

{ // do something throw e; }

At the client side this results in an error message like this:

[junit] Failed to communicate. Problem during marshalling/unmarshalling; nested exception is:
[junit] java.io.InvalidClassException: javax.ejb.EJBException; local class incompatible: stream classdesc serialVersionUID = 2512003687642492863, local class serialVersionUID = 796770993296843510

If I change the code above to sommething like this

catch (Exception e)

{ // do something throw new Exception e; }

Everything works, the exception is passed to the client without any problem.
