Subject [jira] Closed: (UIMA-1680) Async Scaleout Monitor has many issues
Date Wed, 07 Apr 2010 17:18:34 GMT

     [ https://issues.apache.org/jira/browse/UIMA-1680?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jerry Cwiklik closed UIMA-1680.
-------------------------------

    Resolution: Fixed

Fixed the source of NPE in the JmxMonitor class. Updated documentation to remove a comment
that says that the -Duima.jmx.monitor.interval=xx is optional. Tested on Linux platform and
see no problems.
