Note that sanselan was renamed as commons imaging. However the package names were also changed so I'm not sure why they are shown as duplicates. sanselan: org.apache.sanselan imaging: org.apache.commons.imaging Perhaps the information has been derived from SVN rather than the published releases. In which case I suspect there are a lot of false positives. Not all SVN (or Git) source code is part of a release, and source code may go through various name changes. > Sometimes a measurement and visualization is all it takes to realize a > problem and begin fixing it.
