Subject [jira] [Resolved] (UIMA-6135) Ruta: NullPointerException is thrown when closing the Eclipse UIMA annotation editor
Date Mon, 21 Oct 2019 17:03:00 GMT

     [ https://issues.apache.org/jira/browse/UIMA-6135?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Viorel Morari resolved UIMA-6135.
---------------------------------
    Resolution: Fixed

fixed bug in the newest Eclipse version. Moved super.dispose() call to the end of the dispose
method so we can access the site to un-register the listeners in both clases AnnotationTreeViewerPage
and FailedViewPage.
