Buggy source:

    if (list == null)     props.put(owner,list=new ArrayList<MemberDeclaration>());
    list.add(md);

Fixed version (ground truth):

  File out=new File(env.getOptions().get("String_Node_Str"));
  AnnotationTypeDeclaration $exposed=(AnnotationTypeDeclaration)env.getTypeDeclaration(Exposed.class.getName());
  Map<TypeDeclaration,List<MemberDeclaration>> props=new HashMap<TypeDeclaration,List<MemberDeclaration>>();
  for (  Declaration d : env.getDeclarationsAnnotatedWith($exposed)) {
    MemberDeclaration md=(MemberDeclaration)d;
    TypeDeclaration owner=md.getDeclaringType();
    List<MemberDeclaration> list=props.get(owner);
    if (list == null)     props.put(owner,list=new ArrayList<MemberDeclaration>());
    list.add(md);
  }
  for (  Entry<TypeDeclaration,List<MemberDeclaration>> e : props.entrySet()) {
    final Properties javadocs=new Properties();
    for (    MemberDeclaration md : e.getValue()) {
      md.accept(new SimpleDeclarationVisitor(){
        public void visitFieldDeclaration(        FieldDeclaration f){
          String javadoc=f.getDocComment();
          if (javadoc != null)           javadocs.put(f.getSimpleName(),javadoc);
        }
        public void visitMethodDeclaration(        MethodDeclaration m){
          String javadoc=m.getDocComment();
          if (javadoc != null)           javadocs.put(m.getSimpleName() + "String_Node_Str",javadoc);
        }
      }
);
    }
    try {
