Subject [jira] [Commented] (LUCENENET-529) ArgumentOutOfRangeException exception in Lucene.Net.Spatial.Util.FixedBitSet
Date Tue, 03 Dec 2013 22:06:36 GMT

    [ https://issues.apache.org/jira/browse/LUCENENET-529?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13838240#comment-13838240
] 

Itamar Syn-Hershko commented on LUCENENET-529:
----------------------------------------------

This makes sense - I'm going to push this change without the FixedBitSet increment, can you
see if this still fixes the issue?

Also, do you have a test reproducing this that we can add to our suite?

> When the FixedBitSet is created it is initialized to MaxDoc length, however MaxDoc should
be a valid index in the set. Either the indices need to be modified in the Get and Set methods
or the set is grown by 1. Growing the set  requires the fewest code changes elsewhere.
