Ken Krugler commented on TIKA-1581:
-----------------------------------
Based on what I see in other projects (e.g. the Lucene NOTICE.txt file) this
seems to be following standard practices, so I'm going to assume it's OK.
> jhighlight license concerns
> ---------------------------
>
> Key: TIKA-1581
> URL: https://issues.apache.org/jira/browse/TIKA-1581
> Project: Tika
> Issue Type: Bug
> Affects Versions: 1.7
> Reporter: Karl Wright
> Fix For: 1.8
>
>
> jhighlight jar is a Tika dependency. The Lucene team discovered that, while
> it claims to be a CDDL/LGPL dual-license, some of its functionality is LGPL
> only:
> {code}
> Solr's contrib/extraction contains jhighlight-1.0.jar which declares itself
> as dual CDDL or LGPL license. However, some of its classes are distributed
> only under LGPL, e.g.
> com.uwyn.jhighlight.highlighter.
> CppHighlighter.java
> GroovyHighlighter.java
> JavaHighlighter.java
> XmlHighlighter.java
> I downloaded the sources from Maven
> (http://search.maven.org/remotecontent?filepath=com/uwyn/jhighlight/1.0/jhighlight-1.0-sources.jar)
> to confirm that, and also found this SVN repo:
> http://svn.rifers.org/jhighlight/tags/release-1.0, though the project's
> website seems to not exist anymore (https://jhighlight.dev.java.net/).
> I didn't find any direct usage of it in our code, so I guess it's probably
> needed by a 3rd party dependency, such as Tika. Therefore if we e.g. omit it,
> things will compile, but may fail at runtime.
> {code}
> Is it possible to remove this dependency for future releases, or allow only
> optional inclusion of this package? It is of concern to the ManifoldCF
> project because we distribute a binary package that includes Tika and its
> required dependencies, which currently includes jHighlight.
