UIMA AS 2.8.1 Bug: Service does not exit after quiesce via JMX

[Ch...@t-systems.com]

Hi all,

I think the functionality to quiesce a deployed AE via JMX is not implemented correctly.

I did the following steps:

-          Deploy AE via shell script

-          Enable JMX monitor by passing parameters to JVM -Duima.jmx.monitor.interval=60000 -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=8009 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false

-          Connect via JConole and navigate to org.apache.uima -> ee.jms.service -> <Your Annotator Name> Uima EE Service -> Controller -> Operations

-          Run operation completeProcessingAndStop()

Result:

-          The Java process does not exit correctly, because the JMXMonitor thread is still running

Reason:

-          If you quiesce the service via console q + ENTER or s + ENTER the method stopMonitor in class UIMA_Service is explicit executed

-          If you quiesce the service via JMX and running operation StopNow() a System.exit(0) is executed, which kills the JMXMonitor thread

-          If you run operation completeProcessingAndStop() via JMX the JMXMonitor thread is not closed and this is the reason for the bug.


I hope this information will help you to test the behavior. Please feel free to contact me for further details and questions.

Christopher Schulz.

Christopher, thanks for submitting detailed description of the problem. I
will test the scenario and create a JIRA to fix it in the next release.
