Bug 148993 [Workbench] Wrong Javadoc for IDE.getEditorDescriptor
3.2 and latest 3.3 build The Javadoc of IDE.getEditorDescriptor(...) does not mention that as a very last resort it tries to find the editor descriptor for the default text editor i.e. IDEWorkbenchPlugin.DEFAULT_TEXT_EDITOR_ID (org.eclipse.ui.DefaultTextEditor)
bundles/org.eclipse.ui.ide/src/org/eclipse/ui/ide/IDE.java
*                if the editor could not be initialized
	 * 
	 * @see org.eclipse.ui.IWorkbenchPage#openEditor(IEditorInput, String)
	 * @see EFS#getStore(URI)
	 * 
	 * @since 3.3
	 */
	public static IEditorPart openEditor(IWorkbenchPage page, URI uri,
			String editorId, boolean activate) throws PartInitException {
		
		if (page == null) {
			throw new IllegalArgumentException();
		}
		IFileStore fileStore;
		try {
			fileStore = EFS.getStore(uri);
		} catch (CoreException e) {
			throw new PartInitException(
					IDEWorkbenchMessages.IDE_coreExceptionFileStore, e);

	/**
	 * Create the Editor Input appropriate for the given <code>IFileStore</code>.
	 * The result is a normal file editor input if the file exists in the
	 * workspace and, if not, we create a wrapper capable of managing an
	 * 'external' file using its <code>IFileStore</code>.
