Subject [jira] Resolved: (LUCENE-1199) NullPointerException in IndexModifier.close()
Date Sun, 02 Mar 2008 23:35:50 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-1199?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Michael McCandless resolved LUCENE-1199.
----------------------------------------

       Resolution: Fixed
    Fix Version/s: 2.4

OK I just committed a defensive check that indexReader != null before we close it.

But note that IndexModifier is now deprecated and will be removed in 3.0.
