Subject [jira] [Commented] (LUCENE-152) [PATCH] KStem for Lucene
Date Tue, 17 May 2011 00:24:47 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-152?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13034450#comment-13034450

Hoss Man commented on LUCENE-152:
---------------------------------

bq. even if its Apache 2 licensed code. 

Uh... that may be a stretch.

More specifically: compile time dependencies on compiled BSD libraries are fine, but actually
incorporating and *releasing* code that is under a BSD license is something we're aren't suppose
to do (last time i checked)
