[jira] [Commented] (UIMA-5977) DUCC Web Server (WS) JMX thread leak

    [ 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.
