Subject [jira] [Created] (UIMA-3594) UIMA-AS not stopping Listener executor on shutdown
Date Fri, 31 Jan 2014 16:56:09 GMT
Jerry Cwiklik created UIMA-3594:

             Summary: UIMA-AS not stopping Listener executor on shutdown
                 Key: UIMA-3594
                 URL: https://issues.apache.org/jira/browse/UIMA-3594
             Project: UIMA
          Issue Type: Bug
          Components: Async Scaleout
    Affects Versions: 2.4.2AS
            Reporter: Jerry Cwiklik
            Assignee: Jerry Cwiklik
             Fix For: 2.5.0AS

There appears to be a thread leak in the uima-as jms listener. When running extended tests,
the number of threads seem to increase over time. It looks like Executor plugged in into Spring
Listener is not being shutdown sometimes leaving its thread(s) running. 

The listener threads run as daemon threads so on jvm exit they are shutdown. So this leak
may only effect applications that deploy/undeploy collocated (same jvm) UIMA-AS services.
