NoClassDefFoundError on net.sf.freecol.FreeCol about toradocu HOT 1 CLOSED

The problem stems from the fact that Toradocu requires only the binaries of the system under analysis (through the option --class-dir. Those binaries can be incomplete, for example when the system under analysis relies on third-party libraries to implement some of its functionalities. In this case, reflection APIs can throw exception at some point. For an example, look at the following code using the ParseException class from Apache Commons CLI:

package pkg;

import org.apache.commons.cli.ParseException;

public class AClass {
  public static void main(String[] args) {
    try {
      Class<?> clazz = Class.forName("pkg.AClass");
      clazz.getMethods(); // Throws ClassNotFoundException if ParseException binary is not on the classpath.
      throw new ParseException(""); // To make the ParseException catch block legal.
    } catch (ClassNotFoundException e) {
    } catch (ParseException e) {}
  }
}

A possible solution is to require all the binaries (i.e., the system under analysis' classpath).
