Comment:
 Non-free *.class and *.jar files and external libraries were removed from this
 version of JChart2D since they are already packaged for Debian. One java
 source file was possibly not licensed under LGPL-2.1, the other one was
 obsolete.
 jchart2d/test/info/monitorenter/gui/chart/TestChartOperationsVisual.java has
 no license header but it is also licensed under LGPL-2.1+.
 See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=626243#79
 for a clarification from the upstream developer.
