Exception Propagation From Server to Client [INT-3371]

David P Shenba opened INT-3371 and commented

I wish there could be a common exception handling mechanism in Spring Integration. Much like the client Gateway Interface method should be declared with "throws custom-wrapper-exception". In the server side, whenever an exception happens, using interceptors or transformers or automatically, the exceptions should be wrapped to target exception type and sent back to client. In the client side, wherever the gateway method is invoked, it should be surrounded with try catch or the exception should be thrown to next layer. By this there will be clean exception handling in conventional way, instead of getting exception as a normal reply and trying to cast/interpret it in client side.

Start with the linked Spring forum discussion and the server/client gateway behavior described in the issue; no files or tests are named. Clarify the intended exception contract and affected gateway paths, then verify that the agreed behavior propagates server failures as client exceptions rather than normal replies.
