Following steps were done before the IDE goes into the deadlock:

- Start IDE with a fresh userdir 
- Create a JSF project
- From the project properties, add VW framework to the project
- Right click on Web Pages to create a new VW page
- From the Projects window, right click to Source Packages -> New Java Package
  (e.g. name it my_package)
- Right click Page2.java -> Move  (move page to the new package)
- Rename the package name to my_package_r
  (I notice that my_package_r is created under the Web folder along with my_package)
  Since the refactoring code is not fully implemented yet in the Web folder, I decide
  to clean the package.
- Delete my_package_r from Source Packages and Web folders
- Close the project and open recent project
  Opening the project puts the IDE into the deadlock.
