-----------------------------------
Summary: UIMA-AS should not be using System.exit()
Key: UIMA-3905
URL: https://issues.apache.org/jira/browse/UIMA-3905
Project: UIMA
Issue Type: Bug
Components: Async Scaleout
Reporter: Jerry Cwiklik
Assignee: Jerry Cwiklik
Fix For: 2.6.1AS
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.
