We were discussing having Failures being sent to the client for errors, 
instead of strings, probably as Copyables - but first I gotta do 
Copyables for Java PB. Patches accepted :)

Until then - perhaps you should have a special return code indicating 
the method failed? E.g. have response code such as SUCCESS = 1, FAILURE 
= 2, NOACCESS = 0 or something, instead of depending on exceptions.
