Unit testing support is provided by JUnit, under the Common Public License Version 1.0: http://www.opensource.org/licenses/cpl.php See http://www.junit.org/ A single resource file of the POI scratchpad component HDGF is taken from VSDump, and is under the GNU General Public Licence version 3 (GPL v3): http://gplv3.fsf.org/ Since this is a data file, and has no compiled version (the original file is distributed in both source and binary versions of POI), there should be little difference in licencing requirements compared to the ASL. For those wishing to avoid this component, the HDGF part of the POI scratchpad should be omitted.
