> There are a few places where UIMA-AS calls System.exit(). This should be removed and a different approach is needed to force the cleanup. 
> In one scenario, the UIMA-AS terminates when configured error threshold is reached for AE. In another, the UIMA-AS catches java Error like OOM .
> If the UIMA-AS is deployed in a Tomcat container for example the exit() kills the jvm which is a big issue. 
> To support embedding in applications, the UIMA-AS must provide a better way to deal with termination state. One possible approach could be to notify the service wrapper/container that a fatal state has been detected and have the container call stop to clean things up.
