UIMA AS should provide a way to change the Process Timeout dynamically

             Project: UIMA
          Issue Type: New Feature
          Components: Async Scaleout

There is a need to provide a finer level of control over the Process Timeout setting. Currently, UIMA AS client's Process Timeout defaults to 60 secs and can be overriden by an application during initialization of the client. Once set, it remains the same for the duration of the client. There is no way to change it in the middle of the run. Some applications may need to adjust the timeout on per CAS basis. The same functionality (dynamically controlled timeout) may also be useful for UIMA AS services. The exact mechanism for implementing this new feature is up for debate. For UIMA AS client, perhaps a new client API can be added to change the timeout value. The application would change the timeout, call send ( synchronous or asynchronous), and change the timeout value back to what it was when the reply is received. Another approach would be to add the timeout value to the CAS and have the UIMA AS client check for it before forwarding the CAS to a service. Yet another approach would be JMX, although this seems cumbersome.
