Eclipse project to reproduce the bug

Dear Eclipse users, members, and comitters,

We are experiencing a "chaotique" functioning of the Type hierarchy indexing in Eclipse since 3.7 and even more with 4.2. Note that we never had this problem before. So we think this is bug.

The problem is that sometimes when we have a class implementing an interface, pressing F4 on either the class or the interface will not show its supertype or its child class in the Hierarchy view. And the ctrl-T will neither work on a method declaration in the interface. 

I mentionned "chaotique" because it is only doing it for few classes. Our project contains dozens of other interfaces/classes for which the Hierarchy does work. 

However, it is always doing it for the same classes, so hopefully we were able to reproduce this bug. We isolated those classes, took out 99% of our project to clean this up, made a nice zip file, and attached it to this report. Normally, you should be able to reproduce this bug in your environment.

Our environment is: 
- Eclipse Juno SR1 (Build id: 20121004-1855)
- Using JDK 1.6.0_34
Optionaly:
- This project used to be a web app running on a tomcat server 5.5. It's totally not workable/launchable has you have it here, but this is not the goal here.

To see the bug:
- Open the project in Eclipse
- Goto the MyDAOImpl.java file 
- Press F4 -> You should see that the hierarchy window shows no parents, when there should be BaseDAOImpl and MyDAO
- Same if you go in the MyDAO class

Now the strange things:
- Deleting the comments /** ... */ before the getC() function 
- or Deleting the getD() and getD2() functions 
- or Deleting the package-info.java 
will make the hierarchy work again ..... this looks really strange to us. 

I guess some others "actions" can make the hierarchy work again but I didn't find them all. In the case it is really a bug, hopefully they can help investigate on this.

If you need any more details or have any remarks please don't hesitate to ask.

Maxime
