[jira] Commented: (LUCENE-740) Bugs in
contrib/snowball/.../SnowballProgram.java -> Kraaij-Pohlmann gives
Index-OOB Exception
[ https://issues.apache.org/jira/browse/LUCENE-740?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12501703 ]
Steven Parkes commented on LUCENE-740:
--------------------------------------
Do we want to consider this a candidate for 2.2? In any case, the license files in the patch could be applied, since 2.2 seems to be catching lots of those.

> Priority: Minor
> Attachments: 740-license.txt, lucene-1.9.1-SnowballProgram.java, snowball.patch.txt

>
> (copied from mail to java-user)
> while playing with the various stemmers of Lucene(-1.9.1), I got an
> index out of bounds exception:
> lucene-1.9.1>java -cp
> build/contrib/snowball/lucene-snowball-1.9.2-dev.jar
> net.sf.snowball.TestApp Kp bla.txt

> build/contrib/snowball/lucene-snowball-1.9.2-dev.jar
> net.sf.snowball.TestApp Kp bla.txt
> bla.txt contains just this word: 'spijsvertering'.
> After some debugging, and some tests with the original snowball
> distribution from snowball.tartarus.org, it seems that the attached
> change is needed to avoid the exception.
> (The change comes from tartarus' SnowballProgram.java)
