> Current UIMA AS client error handling is not configurable. Specifically, the code tries
to auto-recover from broker failures which may not be ideal for every application. If an application
has an outstanding CAS when the broker fails, the only mechanism is a timeout on a CAS. This
works, but it forces the application to wait for the timeout to occur which may be take a
long time. The client should allow an application to specify how to deal with JMS errors.
Perhaps even other exceptions as well (not just JMS exceptions). One way would be to let the
application provide a list of exceptions and an action to take for each. Another approach
would be to allow the application to register an error handler and have that code deal with
errors. Looking for comments ...
