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.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/wizards/buildpaths/BuildPathsBlock.java
monitor= new NullProgressMonitor();
		}				
		monitor.beginTask(NewWizardMessages.getString("BuildPathsBlock.operationdesc_project"), 10); 
		
		try {
			if (!project.exists()) {
				IProjectDescription desc= project.getWorkspace().newProjectDescription(project.getName());
				if (Platform.getLocation().equals(locationPath)) {
					locationPath= null;
				}
				desc.setLocation(locationPath);
				project.create(desc, monitor);
				monitor= null;
			}
			if (!project.isOpen()) {
				project.open(monitor);
				monitor= null;
			}
		} finally {
			if (monitor != null) {
				monitor.done();
			}
		}
	}
	public static void addJavaNature(IProject project, IProgressMonitor monitor) throws CoreException {
		if (!project.hasNature(JavaCore.NATURE_ID)) {
			IProjectDescription description = project.getDescription();
			String[] prevNatures= description.getNatureIds();
			String[] newNatures= new String[prevNatures.length + 1];
			System.arraycopy(prevNatures, 0, newNatures, 0, prevNatures.length);
