UIMA AS service serializes Exception object which may contain user defined
Exception class not available to the client
----------------------------------------------------------------------------------------------------------------------
Key: UIMA-2304
URL: https://issues.apache.org/jira/browse/UIMA-2304
Project: UIMA
Issue Type: Bug
Components: Async Scaleout
Reporter: Jerry Cwiklik
Assignee: Jerry Cwiklik
Fix For: 2.4.0SDK
When AE throws an exception UIMA wraps it in AnalysisEngineProcessException
which is handed off to UIMA AS. This exception is subsequently serialized as a
java object and sent in a reply to the client. The client deserializes the
cargo back to a java Exception and hands it off to the application via a
callback. The problem is that the Exception stack trace may include user
defined Exception class(es) which are not available to the client thus causing
ClassNotFound while deserializing a reply. Modify UIMA AS service side to
serialize an exception to a String and send that to the client.
