[Java] Class TextUndoManager

    java.lang.Object
      javax.swing.undo.AbstractUndoableEdit
          javax.swing.undo.CompoundEdit
              javax.swing.undo.UndoManager
                  groovy.ui.text.TextUndoManager

    public class TextUndoManager
    extends UndoManager

To use this, simply drop this as an UndoableEditListener into your document, and then create actions to call undo/redo as needed (checking can undo/redo first, of course).
