Subject [jira] [Commented] (LUCENENET-529) ArgumentOutOfRangeException exception in Lucene.Net.Spatial.Util.FixedBitSet
Date Mon, 02 Dec 2013 14:57:37 GMT

    [ https://issues.apache.org/jira/browse/LUCENENET-529?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13836568#comment-13836568

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

Haven't looked yet, but iirc this file is a line-by-line port like the rest of the new spatial
package which I ported last year. You can use the original Java sources to compare.

> 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.
