["Njal Karevoll (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LUCENE-3417?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13098313#comment-13098313 ] 

Njal Karevoll commented on LUCENE-3417:
---------------------------------------

The above patch is trivial to backport for 3.3/3.4.

It is similar to LUCENE-3038, but is not duplicated by LUCENE-3022, which deals with issues surrounding the interpretation of onlyLongestMatch.

> Due to an off-by-one error, a subword placed at the end of a compound word will not get a token added to the token stream.
> Example:
> Dictionary: {"ab", "cd", "ef"}
> word: "abcdef"
> Created tokens: {"abcdef", "ab", "cd"}
> Expected tokens: {"abcdef", "ab", "cd", "ef"}
> Additionally, it could produce tokens that were shorter than the minSubwordSize due to another off-by-one error.
