Buggy source:

Fixed version (ground truth):
public synchronized int run(List<XValue> args) throws Exception {
  SerializeOpts serializeOpts=getSerializeOpts();
  ClassLoader classloader=null;
  if (args.size() > 1) {
    String arg1=args.get(0).toString();
    if (arg1.equals("String_Node_Str") || arg1.equals("String_Node_Str")) {
      args.remove(0);
      XValue classpath=args.remove(0);
      classloader=getClassLoader(classpath);
    }
  }
  if (classloader == null)   classloader=getClassLoader(null);
  SecurityManager oldManager=null;
  if (args.size() < 1)   throw new InvalidArgumentException("String_Node_Str");
  PrintStream stdout=System.out;
  InputStream stdin=System.in;
  PrintStream newStdout=null;
  try {
    oldManager=System.getSecurityManager();
    System.setSecurityManager(new NoExitSecurityManager(oldManager));
    System.setOut(newStdout=getStdout().asPrintStream(serializeOpts));
    System.setIn(getStdin().asInputStream(serializeOpts));
    String className=args.remove(0).toString();
