Improve Exception Handling Documentation

[feinstein]

As I state on my Stackoverflow question, I can't find any information about Jersey's behavior on uncaught Exceptions (Exceptions that aren't WebApplicationException and neither have been mapped with ExceptionMapper).

It would be great to know what's the expected behavior of some Exception that slips from our control and finds the Jersey container. This is specially important for security reasons, for systems that don't want to expose to the clients any kind of inner system state or variables.

I know it will take some time for this documentation to be made, so if possible, I would like to ask someone from the dev team to answer my Stackoverflow question, this will be very helpful for me and I believe for many others.
