Subject [jira] Commented: (LUCENENET-157) SegmentMerger.AddIndexed() performs an illegal cast
Date Wed, 08 Oct 2008 18:03:44 GMT

    [ https://issues.apache.org/jira/browse/LUCENENET-157?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12638010#action_12638010
] 

Digy commented on LUCENENET-157:
--------------------------------

I think, it would be better to change the GetFieldNames methods in ParallelReader, SegmentReader
and MultiSegmentReader so that they return
ICollection not IDictionary 
(like return hashTable --> return hastTable.Keys)

> 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).
