Hi Bill,

My specific concern was that client applications had to deal
ClientException *AND* MessageProcessingException. I think earlier
versions of the API used both exceptions in different places within the
API.

IMO, still, clients should only deal with 2 types of exceptiosn:
ClientException and WebApplicationException. In other words, these two
exceptions should be the base classes for an exception hierarchy.

NotFoundException extends WebApplicationException
ConnectionFailure extends ClientException
ClosedConnectionFailure extends ClientException
ReaderFailure extends ClientException
WriterFailure extends ClientException

Now, if you ditch ClientException and have a shared
MessageProcessingException, you can re-use these exception hierarchies
within MBR, MBW, and Reader/WriterInterceptor both on the client and
server side. ***Client code would not have to deal with wrapped
exceptions and could catch them directly.

So, I'm suggesting ditch ClientException and use
MessageProcessingException instead. Build an additional
non-wire/non-response exception hierarchy off of
MessageProcessingException.


Having more ClientException subclasses does make sense to me, I recall
Marek was also in favor, however I'm not keen on the idea of
MessageProcessingException serving as the base exception even for
client-centric exceptions...


Still, I despise the idea of having to call getCause() to check if a specific error condition exists. Its just bad design.
