 - JGraphT requires JDK 1.8 or later to build starting with version 1.0.0.
-- [JUnit](http://www.junit.org) is a unit testing framework. You need JUnit only if you want to run the unit tests.  JUnit is licensed under the terms of the IBM Common Public License.  The JUnit tests included with JGraphT have been created using JUnit `3.8.1`.
-- [XMLUnit](http://xmlunit.sourceforge.net) extends JUnit with XML capabilities. You need XMLUnit only if you want to run the unit tests.  XMLUnit is licensed under the terms of the BSD
-    License.
-- [JGraph](http://sourceforge.net/projects/jgraph) is a graph visualization and editing component. You need JGraph only if you want to create graph visualizations using the JGraphT-to-JGraph adapter. JGraph is licensed     under the terms of the GNU Lesser General Public License (LGPL). 
-- [JGraphX](http://www.jgraph.com/jgraph.html) is the successor to JGraph. You need JGraphX only if you want to use the JGraphXAdapter to visualize the JGraphT graph interactively via JGraphX. JGraphX is licensed under the terms of the BSD license.
+- [JUnit](http://www.junit.org) is a unit testing framework. You need JUnit only if you want to run the unit tests.  JUnit is licensed under the terms of the IBM Common Public License.  The JUnit tests included with JGraphT have been created using JUnit 4.

+- [JGraphX](http://www.jgraph.com/jgraph.html) is a graph visualizations and editing component (the successor to the older JGraph library). You need JGraphX only if you want to use the JGraphXAdapter to visualize the JGraphT graph interactively via JGraphX. JGraphX is licensed under the terms of the BSD license.
 - [Touchgraph](http://sourceforge.net/projects/touchgraph) is a graph visualization and layout component. You need Touchgraph only if you want to create graph visualizations using the JGraphT-to-Touchgraph converter. Touchgraph is licensed under the terms of an Apache-style License.
 - [ANTLR](http://www.antlr.org) is a parser generator.  It is used for reading text files containing graph representations, and is only required by the jgrapht-io module.  ANTLR v4 is licensed under the terms of the [BSD license](http://www.antlr.org/license.html).
