[jira] [Commented] (LUCENE-4656) Fix EmptyTokenizer

JIRA jira@apache.org

    [ https://issues.apache.org/jira/browse/LUCENE-4656?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13542987#comment-13542987 ]

Uwe Schindler commented on LUCENE-4656:
---------------------------------------

bq. I needed to add a quick hack to add a TermToBytesRefAttribute when the tokenstream doesn't have one so that TermsHashPerField doesn't complain that it can't find this attribute when indexing.

But this is a bug. If you use the non-test EmptyTokenStream from the analysis-common package and add it to a document it will fail, right? So we should fix IndexWriter to handle that case?

> TestRandomChains can fail because EmptyTokenizer doesn't have a CharTermAttribute and doesn't compute the end offset (if the offset attribute was added by a filter).
