Subject [jira] Commented: (LUCENENET-157) SegmentMerger.AddIndexed() performs an illegal cast
Date Wed, 08 Oct 2008 20:29:44 GMT

    [ https://issues.apache.org/jira/browse/LUCENENET-157?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12638062#action_12638062

Doug Sale commented on LUCENENET-157:
-------------------------------------

I am OK with the change you suggested.  However, there are a number of other classes that
need to change, in addition to other changes in the files the provided patch touches.  Applying
AnotherPatch.rar (SegmentReader.patch, ParallerlReader.patch, and MultiSegmentReader.patch)
leads to 17 unit test failures from runtime incompatibilities.  I have addressed these issues
and will upload the patch momentarily.

> This is an error introduced via the JLCA (automated porting process) and stems from the
use of System.Collections.Hashtable in the role of java.util.HashSet.
> SegmentMerger.AddIndexed() is passed a Hashtable as its 3rd argument, but treats it as
if it were a 1-dimensional collection (e.g., IList).
