Bug 180758 [IDE] Deleting a project but not the contents asks if you want to delete read-only files
I have noticed that in 3.3M6, if I delete a project that has read-only files in it, it will prompt if I want to delete the files even if I select "Do not delete contents". The files are not actually deleted, but the error dialog should not be presented to the user since the files are not actually being deleted. I don't remember seeing this in 3.3M4 or earlier.

static class DeleteProjectDialog extends MessageDialog {
		private IResource[] projects;
		private boolean deleteContent = false;
		/**
		 * Control testing mode. In testing mode, it returns true to delete
		 * contents and does not pop up the dialog.
		 */
		private boolean fIsTesting = false;
		private Button radio1;
		private Button radio2;
		DeleteProjectDialog(Shell parentShell, IResource[] projects) {
			super(parentShell, getTitle(projects), null, 
					
					
					getMessage(projects), MessageDialog.QUESTION, new String[] {
							IDialogConstants.YES_LABEL,
							IDialogConstants.NO_LABEL }, 0);
