The exception says :

2.Delete the entire A project from the Package Explorer
3.Try to close the opened file related to the project A

Alessio, I think your steps are incomplete. I suspect that you did something like this:

1. opened editor(s)
2. exit Eclipse
3. start Eclipse
4. delete the project
5. click on an editor tab of a deleted file
==> exceptions.

Steps to reproduce :

1) Open Eclipse, create a project and some java files inside it.
2) Open some files in the Java Editor 
3) Close eclipse
4) Open Eclipse (you will find your files opened as you leave it when previously closed eclipse)
5) Go in Package explorer 
6) Select the project which that opened files belongs.
7) Delete the project 


I've reproduced this error on Mac OS X Lion, Windows 7, Debian 6 Squeeze .

After (auto-) closing the active editor, the workbench tries to activate an editor whose file is also part of the deleted project. And this what bug 186977 covers.
