  menuSelectall.getActionMap().get(DefaultEditorKit.selectAllAction)
  menuSelectall.setText("Select All");

You don't use a MouseListener to handle events on a popup menu, the menu item should already be created with the specific Action.

You just create a JMenuItem using the Action from the EditorKit and then you add the menu item to your JPopupMenu. The code should be something like:

JMenuItem selectAll = new JMenuItem( textarea.getActionMap().get(DefaultEditorKit.selectAllAc‌​tion) );
popupMenu.add( selectAll );

The menu item will than handle the mouse event and invoke the Action.
