Subject [jira] [Commented] (UIMA-5977) DUCC Web Server (WS) JMX thread leak
Date Fri, 01 Feb 2019 16:04:00 GMT

    [ https://issues.apache.org/jira/browse/UIMA-5977?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16758444#comment-16758444

Lou DeGenaro commented on UIMA-5977:
------------------------------------

WS code for JMX connection management comprises JmxHelper and derived classes BrokerHelper
and DatabaseHelper.  The code to to "reconnect" is inconsistent.  Fix is to abandon "reconnect"
(which may not close previous connection) in favor of connect+disconnect.  Tested, and problem
is fixed.
