Subject [jira] [Updated] (SOLR-7866) getMaxVersionFromIndex is throwing an NPE if some segments are not current
Date Wed, 05 Aug 2015 04:13:04 GMT

     [ https://issues.apache.org/jira/browse/SOLR-7866?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Timothy Potter updated SOLR-7866:
---------------------------------
    Priority: Major  (was: Blocker)

Dropping this ticket from Blocker for 5.3 to major status as I haven't been able to reproduce
this issue. We could of course just code around this issue by catching the NPE but given that
I can't reproduce it with empty / non-empty 4.x and 5.x indexes, I'm hesitant to change code
in this area until LUCENE-6719 is resolved.
