Bug 39272 Java Model Exception when creating a project from scratch
I launched Eclipse 2.1 from a brand new Workspace and from there, created a Java project (called "Works") by pointing Eclipse to the root of my project. The process fails after a short while (whether I press Next or Finish after the first page of the wizard) with a dialog telling me to look at the log. I included the top of the log below (it's about 8k, I can post it in its entirety if there's interest). The error is Java Model Exception: Java Model Status [Works does not exist.] I get the same problem with Eclipse 3.0 M1: I can't create a new project.

		fContext= context;
		
		fPageIndex= pageToShow;
		
		
		fSourceContainerPage= null;
		fLibrariesPage= null;
		fProjectsPage= null;
		fCurrPage= null;

			 null,
			 NewWizardMessages.getString("BuildPathsBlock.classpath.checkall.button"), 
			 NewWizardMessages.getString("BuildPathsBlock.classpath.uncheckall.button") 
		
		};
		
		fClassPathList= new CheckedListDialogField(null, buttonLabels, new CPListLabelProvider());
		fClassPathList.setDialogFieldListener(adapter);
		fClassPathList.setLabelText(NewWizardMessages.getString("BuildPathsBlock.classpath.label"));  
		fClassPathList.setUpButtonIndex(0);
		fClassPathList.setDownButtonIndex(1);
		fClassPathList.setCheckAllButtonIndex(3);
