Buggy source:

Fixed version (ground truth):

  final ProjectInformationImpl projectInformationImpl=projectImpl.getLookup().lookup(ProjectInformationImpl.class);
  final WorkspaceProviderImpl workspaceProviderImpl=project.getLookup().lookup(WorkspaceProviderImpl.class);
  if (projects.hasCurrentProject()) {
    if (!closeCurrentProject()) {
      return;
    }
  }
  projects.addProject(projectImpl);
  projects.setCurrentProject(projectImpl);
  projectInformationImpl.open();
  if (!workspaceProviderImpl.hasCurrentWorkspace()) {
    if (workspaceProviderImpl.getWorkspaces().length == 0) {
      Workspace workspace=newWorkspace(project);
      openWorkspace(workspace);
    }
 else {
      Workspace workspace=workspaceProviderImpl.getWorkspaces()[0];
      openWorkspace(workspace);
    }
  }
 else {
    fireWorkspaceEvent(EventType.SELECT,workspaceProviderImpl.getCurrentWorkspace());
  }
  saveProject=true;
  saveAsProject=true;
  projectProperties=true;
  closeProject=true;
  newWorkspace=true;

  SwingUtilities.invokeLater(new Runnable(){
    public void run(){
