Bug 98472 New project wizard: second page remove from class path should ask for removal of folder when linked
RC1 - create a new project - switch to the second page - link in additional source observe: there is no way to unlink the addtional source We should offer to unlink the folder when the folder is removed from the build path again.

* to create a folder.
