[jira] [Commented] (UIMA-2351) Remove busy loop from uima-as JmsInputChannel

    [ https://issues.apache.org/jira/browse/UIMA-2351?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13189276#comment-13189276 ] 

Marshall Schor commented on UIMA-2351:
--------------------------------------

So, this change then requires AMQ at a later than 4.1.1 - do we say that in our documentation?

> Found a busy loop in the JmsInputChannel which continually checks the state of the jms listener in a dedicated thread. If I remember this was put in to deal with shutdown of AMQ4.1.1 threads which were set to run as daemon threads. Since 4.1.1, AMQ no longer uses daemon threads so no reason to use this code.
