[jira] [Commented] (LUCENE-5187) Make SlowCompositeReaderWrapper constructor private

    [ https://issues.apache.org/jira/browse/LUCENE-5187?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13748521#comment-13748521 ] 

Robert Muir commented on LUCENE-5187:
-------------------------------------

+1

In the case of grouping tests, is it really safe to change this way?

{noformat}
       // NOTE: intentional but temporary field cache insanity!
-      final FieldCache.Ints docIdToFieldId = FieldCache.DEFAULT.getInts(new SlowCompositeReaderWrapper(r), "id", false);
+      final FieldCache.Ints docIdToFieldId = FieldCache.DEFAULT.getInts(SlowCompositeReaderWrapper.wrap(r), "id", false);
{noformat}

if needed, Maybe instead, we should force compositeness by e.g. inserting an empty reader if necessary or whatever. but i'm not even sure what this test is doing.

> I found a couple of places in the code base that duplicate the logic of SlowCompositeReaderWrapper.wrap. I think {{SlowCompositeReaderWrapper.wrap}} (vs. new SlowCompositeReaderWrapper) is what users need so we should probably make SlowCompositeReaderWrapper constructor private to enforce usage of {{wrap}}.
